PHPBenelux conference 2010 wrapup

2010-02-03T19:11:00.002+01:00

This past weekend, Belgium was buzzing PHP all the way. PHPBenelux organized the first annual international PHP conference in Belgium and it can be called a true success. Attendees and speakers coming from all parts of the world made this event a true international conference and I was truly happy to be a part of it, this time as member of the organization.

Preparation

The months, weeks and certainly the days prior to the conference were hectic, stressful and sometimes energy draining. With lots of things that still needed to be done last minute, we have learned that we still have lots of room to improve ourselves for future events. But, as it is common to PHP development, we met our deadlines and saw everything was running smoothly.

Airport and train station runs

The conference had a few international speakers on the list, for who we had to ensure a smooth ride to the conference hotel. Stefan Koopmanschap picked up Cal Evans at Schiphol. Thijs Feryn went down to Antwerp Central Station to pick up Fabien Potencier, and had to do this 3 times returning each time without Fabien (read his blog article about what happend). I myself went to Brussels International Airport to pick up David Zülke and Rowan Merewood traveling together with Ben Waine.

Speaker's dinner and pre-conference social

As is custom to events like this, we organized as speaker's dinner where we invited our speakers and sponsors to participate in this socializing event where everyone has the opportunity to get to know each other, discuss topics and exchange ideas. We headed out to Da Giovanni, an Italian restaurant in the center of Antwerp that is known for it's overwhelming tacky design. Red-white blocked cloths everywhere: the shirts of the waiters, the tables and lamps. We had a decent meal and a very good laugh.

Following the dinner we also organized a pre-conference social in De Vagant, one of Antwerp's most known Jenever locations. This was open for everyone that was in the area and could make it to the place. But tiredness and pre-conference jitters had this social ended well before midnight.

The conference

Saturday was the big day, and what a day it was ! Sponsors arrived well in time to set up their booths and at about 8:30am the first attendees were coming in. Since it had snowed during the night, most attendees were a bit late so we started the sessions with a delay of 30 minutes (by lunch time we were already back on schedule).

After a short introduction by Stefan Koopmanschap, Derick Rethans officially opened the conference with his keynote talk "The PHP Universe", which was well accepted by the audience (See reviews on http://joind.in/1240). The following talks followed right after and filled the most of the conference.

Fabien Potencier presented "Dependency Injection in PHP 5.2 and 5.3" (http://joind.in/1241) in track 1 while Rowan Merewood talked about "Living with Legacy Code" (http://joind.in/1242) in track 2
David Zülke presented "The State of SOAP in PHP" (http://joind.in/1243) in track 1 while Paul Borgermans talked about "Get the most out of Solr search with PHP" (http://joind.in/1244) in track 2
Juliette Reinders Folmer presented "Reg-Ex Fu" (http://joind.in/1245) in track 1 while Patrick Allaert and Davide Mendolia talked about "PHP applications/environments monitoring: APM & Pinba" (http://joind.in/1246) in track 2
Maarten Balliauw presented "Just another WordPress weblog, but more cloudy" (http://joind.in/1247) in track 1 while Kore Nordmann talked about "PHPillow & CouchDB & PHP" (http://joind.in/1248) in track 2
Lorna Mitchell presented "Passing the Joel Test in the PHP World" (http://joind.in/1249) in track 1 while Ivo Jansch talked about "PHP and the Cloud" (http://joind.in/1250) in track 2

Remote presentation

Due to bad weather, Zend's speaker Eric Ritchie couldn't make it to the conference, but by using WebEx we were able to have him present his talk "Generating dynamic PDFs using Zend Framework and JavaBridge" (http://joind.in/1268) from his office as though he was standing in the room. Although it was a bit tough to set up, I have to say it was successful fix for Zend, WebEx and us.

One downside of this approach is that Eric didn't had the chance to interact with the attendees himself during or after his keynote and as shown in the comments on joind.in there were still a few questions that the attendees wanted to clarify with Eric. So, in a technical perspective it can be called a success, but for the conference spirit it has a downside.

Closing Keynote

My personal mentor and dear friend Cal Evans was given the floor to present his closing keynote "Open Teams" (http://joind.in/1251) which was unlike the other talks not a technical subject, but non-the-less a very valuable view on how managers and developers can improve the way they operate. Unfortunately I missed this talk, but I'm looking forward seeing it on an other occasion. You can contact Cal and invite him to give this talk for the managers in your company, so your company can become "Company Awesome" everyone wants to work for.

Ibuildings Conference Social

The people of Ibuildings were really kind to sponsor the after-social event, held in the exhibition hall. Besides drinks and very delicious food, our other sponsors had some goodies to give away and so people walked away with an iPhone and Zend Studio licenses, a ticket for PHPBenelux Conference 2011, a ticket for PHPUK 2010, Windows 7 licenses, a netbook (provided by Nocus) and of course elePHPants. So a big applause to the winners and of course our sponsors for providing these awesome prizes.

Sponsors

This great conference wasn't possible without the help of our sponsors, and we all thank them for making this first conference the best start of 2010. Thank you !!!

Our sponsors: Zend / Dataflow, Microsoft, Ibuildings, Combell, Telenet, Cu.Be, ServerGrove and WEBclusive.

PHP is hot !

Apparently PHP is hot, hotter then ever. At the conference, a lot of people not only attended the great sessions, but they were also looking for new PHP developers to join their teams. And they were not just giving you a great job, they even offered some real nice goodies when you signed up:

Telenet: HTC Hero (till Friday, February 5 2010) - Apply here
Ibuildings: Apple iPad (till Friday, March 15 2010) - Apply here
DataFlow: Apple iPhone and 3 Zend Studio Licenses (only on the conference day) - Apply here

If you're a company and you're looking for PHP Rock stars, see how you can persuade them to at least talk to you. Make sure you have seen the slides of Cal Evans's talk about "Open Teams", cause if you can offer this, you do have the advantage !

PHPBenelux Team

This conference succeeded because of the never-failing, passionate help and support by the whole PHPBenelux team. I have worked in many teams already, but I have to say that working with these guys on a remote basis (all using Skype, Google docs and e-mail as main communication and collaboration tools) worked very well (as to emphasize what Cal Evans stated in his "Open Teams" talk) and everyone was there to see the result.

Teamies, thanks a lot for this wonderful experience and I'm looking forward doing the things we do best: community relations, meetings and events ! You guys rock !!!

Conclusion

This was the first conference that I not only attended, but was actually involved behind the scenes. It was a great experience and I have now more respect to organizers of bigger conferences now that we know what kind of challenges they have to overcome.

Read what others had to say about our conference:

I had a blast and I hope you all enjoyed it. See you all next year at the PHPBenelux Conference 2011, and let us know how to improve ourselves for next years' conference at joind.in !!!

Zend Framework data models

2010-01-07T17:22:00.000+01:00

I was struggling getting my data models (as described in the Zend Framework Quickstart) to work with relations. My first solution was to create a database view that merged that data using joins to collect this data in a format that I could use in my data models. This was going great until I looked at my database where it contained over 20 views (along with 20 data models, mappers and db table gateways) ! So I said to myself there had to be another way.

Fortunately there was a solution, hinted by Felix De Vliegher on IRC. He pointed me to the Zend Framework Zend_Db_Table Relationships page on the Zend Framework online manual. And although it's clearly specified how things work, I struggled a bit to see how each component was linked to the other and when I should use what.

So, I decided to work out a small application to test and support this relationship modeling.

Step 1: Preparation
Let's start with creating a new Zend Framework project that we call "datamodels".

zf create project datamodels

This creates a new Zend Framework project that we can use to showcase these examples. We add a few directories to the application structure to store our documentation, our database and our schemas.

These are four tables all related to each other that we use to base our tutorial and test upon.

Translated into SQLite3 this looks like this:

-- filename: schema.sqlite.sql --

create table `user` (
    `id` integer primary key autoincrement,
    `username` text not null,
    `password` text not null
);

create table `contact` (
    `id` integer primary key autoincrement,
    `user_id` integer not null,
    `email` text not null,
    `phone` text null,
    `fax` text null
);

create table `address` (
    `id` integer primary key autoincrement,
    `type_id` integer not null default 1,
    `user_id` integer not null,
    `address1` text not null,
    `address2` text null,
    `city` text not null,
    `state` text null,
    `zip` text not null,
    `country` text not null
);

create table `address_type` (
    `id` integer primary key autoincrement,
    `type` text not null
);

Creating the SQLite3 database is now easy as 1,2,3. Just from command line execute sqlite3 ./data/db/datamodels.db < schema.sqlite.sql and see the magic happen. Our database is set and ready to use.

Our test data is also stored in a file, it's contents can be found here:

-- filename: data.sqlite.sql --

-- Data for user table --
INSERT INTO `user` 
    VALUES (1, 'testuser1', 'test123');
INSERT INTO `user` 
    VALUES (2, 'testuser2', 'test234');

-- Data for contact table --
INSERT INTO `contact` 
    VALUES (1, 1, 'test1@example.com', '1-800-555-1234', '1-800-555-1230');
INSERT INTO `contact` 
    VALUES (2, 2, 'test2@example.com', '1-800-555-2234', '1-800-555-2230');

-- Data for address table --
INSERT INTO `address`
    VALUES (1, 1, 1, '1 Test Home', '', 'Testtown', 'ZF', '1234', 'PHP');
INSERT INTO `address`
    VALUES (2, 1, 2, '2 Test Home', '', 'Testtown', 'ZF', '1234', 'PHP');
INSERT INTO `address`
    VALUES (3, 2, 2, 'Test Corp, LTD', '4 Test Ave', 'Testtown', 'ZF', '1234', 'PHP');
    
-- Data for address_type table --
INSERT INTO `address_type`
    VALUES (1, 'Home address');
INSERT INTO `address_type`
    VALUES (2, 'Billing address');

In application/configs/application.ini we need to add the following lines in order to use our newly generated database:

[production]
...
resources.db.adapter = "Pdo_SQLite"
resources.db.params.dbname = APPLICATION_PATH "/../data/db/datamodels.db"

You also need to define our "Default" namespace in the application bootstrap file Bootstrap.php. This is done by adding the following lines there.

protected function _initAutoload()
    {
        $autoloader = new Zend_Application_Module_Autoloader(array (
            'namespace' => 'Default',
            'basePath' => APPLICATION_PATH,
        ));
        return $autoloader;
    }

Creating the four data models along with their mappers and table gateways is a bit of work so I've provided the application as-is on a public SVN repository (https://svn2.hosted-projects.com/in2it/datamodels/tags/step_1). You can export it and start from there.

Step 2: Displaying a user listing
We want to display a listing of users with their contact details and the number of addresses they have, more or less like the following table:

Username	E-mail	Phone	Fax	# addresses
testuser1	test1@example.com	1-800-555-1234	1-800-555-1230	1
testuser2	test2@example.com	1-800-555-2234	1-800-555-2230	2

As you can see now, with this listing we have 3 tables combined and without some relational information between the models it's hard to get this kind of listing.

Let's set up our dbTable classes to work with relationships.

class Default_Model_DbTable_User extends Zend_Db_Table_Abstract
{
    protected $_name = 'user'; 
    protected $_dependentTables = array (
        'Default_Model_DbTable_Contact',
        'Default_Model_DbTable_Address',
    );
}

class Default_Model_DbTable_AddressType extends Zend_Db_Table_Abstract
{
    protected $_name = 'address_type'; 
    protected $_dependentTables = array ('Default_Model_DbTable_Address');
}

class Default_Model_DbTable_Contact extends Zend_Db_Table_Abstract
{
    protected $_name = 'contact';
    protected $_referenceMap = array (
        'User' => array (
            'columns' => array ('user_id'),
            'refTableClass' => 'Default_Model_DbTable_User',
            'refColumns' => array ('id'),
        ),
    );
}

class Default_Model_DbTable_Address extends Zend_Db_Table_Abstract
{
    protected $_name = 'address'; 
    protected $_referenceMap = array (
        'User' => array (
            'columns' => array ('user_id'),
            'refTableClass' => 'Default_Model_DbTable_User',
            'refColumns' => array ('id'),
        ),
        'Type' => array (
            'columns' => array ('type_id'),
            'refTableClass' => 'Default_Model_DbTable_AddressType',
            'refColumns' => array ('id'),
        ),
    );
}

In order to use these relations, we create a new model and mapper for listing these accounts.

class Default_Model_Accounts extends Default_Model_Abstract
{
    protected $_username;
    protected $_email;
    protected $_phone;
    protected $_fax;
    protected $_addressCount;
    
    public function getUsername ()
    {
        return $this->_username;
    }

    public function setUsername ($username)
    {
        $this->_username = (string) $username;
        return $this;
    }

    public function getEmail ()
    {
        return $this->_email;
    }

    public function setEmail ($email)
    {
        $this->_email = (string) $email;
        return $this;
    }

    public function getPhone ()
    {
        return $this->_phone;
    }

    public function setPhone ($phone)
    {
        $this->_phone = (string) $phone;
        return $this;
    }

    public function getFax ()
    {
        return $this->_fax;
    }

    public function setFax ($fax)
    {
        $this->_fax = (string) $fax;
        return $this;
    }

    public function getAddressCount ()
    {
        return $this->_addressCount;
    }

    public function setAddressCount ($addressCount)
    {
        $this->_addressCount = (int) $addressCount;
        return $this;
    }

    public function getMapper()
    {
        if (null === $this->_mapper) {
            $this->setMapper('Default_Model_Mapper_Accounts');
        }
        return $this->_mapper;
    }
    public function populate($row)
    {
        if (is_array($row)) {
            $row = new ArrayObject($row, ArrayObject::ARRAY_AS_PROPS);
        }
        if (isset ($row->id)) {
            $this->setId($row->id);
        }
        if (isset ($row->username)) {
            $this->setUsername($row->username);
        }
        if (isset ($row->email)) {
            $this->setEmail($row->email);
        }
        if (isset ($row->phone)) {
            $this->setPhone($row->phone);
        }
        if (isset ($row->fax)) {
            $this->setFax($row->fax);
        }
    }
    public function toArray()
    {
        return array (
            'id' => $this->getId(),
            'username' => $this->getUsername(),
            'email' => $this->getEmail(),
            'phone' => $this->getPhone(),
            'fax' => $this->getFax(),
            'address_count' => $this->getAddressCount(),
        );
    }
}

class Default_Model_Mapper_Accounts extends Default_Model_Mapper_Abstract
{
    public function getDbTable()
    {
        if (null === $this->_dbTable) {
            $this->setDbTable('Default_Model_DbTable_User');
        }
        return $this->_dbTable;
    }
    
    public function fetchAll($className, $where = null, $order = null, $count = null, $offset = null)
    {
        $entries = array ();
        $model = null;
        if (!is_string($className)) {
            require_once 'Zend/Exception.php';
            throw new Zend_Exception('Model class name should be a string');
        }
        if (is_string($className)) {
            if (!class_exists($className)) {
                require_once 'Zend/Exception.php';
                throw new Zend_Exception('Non-existing model class name provided');
            }
        }
        if (null !== ($resultSet = $this->getDbTable()->fetchAll($where, $order, $count, $offset))) {
            foreach ($resultSet as $row) {
                $model = new $className;
                if (!$model instanceof Default_Model_Abstract) {
                    require_once 'Zend/Exception.php';
                    throw new Zend_Exception('Invalid model class provided');
                }
                
                // let's get contact details first
                $contacts = $row->findDependentRowset(
                    'Default_Model_DbTable_Contact',
                    'User'
                );
                $contact = $contacts->current();
                $model->populate($contact);
                unset ($contacts, $contact);
                
                // let's see how many addresses this contact has
                $addresses = $row->findDependentRowset(
                    'Default_Model_DbTable_Address',
                    'User'
                );
                $addressCount = count($addresses);
                $model->setAddressCount($addressCount);
                unset ($addresses, $addressCount);
                
                // now it's time to add our user details to the model
                $model->populate($row);
                $entries[] = $model;
                unset ($model);
            }
        }
        return $entries;
    }
}

And to view our completed table, we need to modify our view partial userlisting.phtml:

<tr>
  <td><?php echo $this->escape($this->username) ?></td>
  <td><?php echo $this->escape($this->email) ?></td>
  <td><?php echo $this->escape($this->phone) ?></td>
  <td><?php echo $this->escape($this->fax) ?></td>
  <td><?php echo $this->escape($this->address_count) ?></td>
</tr>

Now we have our table set as we want it:

You can download this step from the repo to see the changes yourself: https://svn2.hosted-projects.com/in2it/datamodels/tags/step_2.

Conclusion
Once you have figured out how these relationships work, you can extends your model capabilities without resorting to other solutions (like using database views) or maintaining crappy code.

On the other hand, It would be nice if I could use my already created models with their functionality in one go, so I can link my datamodels instead of my data sources. Need to figure this one out.

A great 2009 !

2009-12-29T12:01:00.000+01:00

It's that time of year again where one looks back to all the things that have happened in the past 12 months. 2009 has to be the most thrilling, fastest ride ever and I'm really surprised to see it's nearly the end of this year.

PHP
The most thrilling part of 2009 was the release of PHP 5.3 on June 30. With this release, PHP has risen to a new level of development implementing some long awaited features like DateTime, namespaces, closures, gotos (who wants to use that ?!?), late static binding and an improved garbage collection. Also new extensions were added to this release like ext/phar, ext/fileinfo and ext/intl.
I want to express my gratitude to all those developers who have made this release possible and to all the participants of PHP Test Fest for making their contributions worth the while.

Zend Framework
It's also worth mentioning that Supreme Allied Commander Matthew Weier O' Phinney, his team and all developers around the world have done a great job improving Zend Framework. With the release of Zend Framework 1.8, lot's of things changed within the way applications are being bootstrapped and provided a more flexible way to deploy feature rich applications with a very modular structure.

PHP Conferences
For me personal it was a very exciting year where I was speaking at some great conferences on stage and in uncon sessions (thank you Keith!). If budget allows it, I'll be attending these conferences again in 2010.

PHP UK (attendee)
PHP|Tek (uncon speaker)
DPC (speaker)
PHP NW (speaker)
ZendCon (uncon speaker)

One conference will be added to this list in 2010 since I'll be co-organizing it: PHPBenelux Conference.
If you ever want to catch up on the hottest game in PHP, be sure to check out these and other great PHP conferences on the PHP website. You'll learn so much from the conference itself, the speakers and the audience itself, it's really worth the money.

Macq Electronique
Since March of this year I've been working as a PHP/Zend Framework consultant for Macq Electronique, a hardware manufacturer in Brussels that provides hardware solutions for governments (like automated traffic panels, speed enforcement cameras, tunnel control and pump installation monitors). I would like to thank the company for giving me inside view of these infrastructures and I'm excited to work with them again in 2010.

Thank you !
I would like to express my gratitude to the following people who have thought me a few valuable lessons that I can use in my personal and professional life:

Cal Evans:
Cal, to you we now have our own PHP conference in January. Without your support, advise and never ending belief in us, we weren't able to pull it off. Thank you !
Matthew Weier O'Phinney:
Matthew, although we never had the chance to sit down and discuss things I do want to thank you for all the good work you have done for Zend Framework and the PHP Community. If it wasn't for you, I'd still be stuck writing crappy code with code replication and re-inventing the wheel all over again. Thank you !
Keith Casey:
Keith, thanks to you I was able to talk about stuff that matters to me and being able to inspire people to become interested in things like SPL and Unit Testing. Thank you !
Stefan Koopmanschap:
Stefan, although it seems I've been giving you lots of advice this year, you have shown me what a true spirit means. With your enormous passion for PHP and your ideas to promote PHP in ways that I never could think possible, I owe you so much. Thank you my friend !
Chris Cornut:
Chris, I would like to thank you for giving us Joind.in. With it's simple interface and it's purpose it has given me so much feedback on how to improve my skills as a speaker. Without it, I would never known what areas I could improve myself. So thank you very much for your efforts !

Conclusion
2009 was a great year and I'm sorry to see it end. But a new year is around the corner and who knows, it might bring even more excitement and fulfillment. Anyways, I wish you all a very happy new year and I hope to see you again at a conference somewhere in the world.

Unit testing with Zend Framework 1.8+

2009-11-01T22:36:00.000+01:00

I recently gave a presentation at ZendCon 2009 Uncon about "php unit with Zend Framework", which many people liked a lot (see comments on http://joind.in/638). But since then I got a lot of questions how to set up a testing environment for Zend Framework applications that uses version Zend Framework 1.8 or newer.

We start off by setting our environment best fitted for our unit testing. I use a virtual linux system for this, using VMWare, but with some extra background research these global settings can be applied for your own (test) environment as well.

I'm not going to explain how to install PHP here, but I can tell you I'm using PHP 5.3.0 (build from source). With this build, I've installed PHPUnit 3.4.2 and Xdebug 2.0.5. The example application was made using Zend Framework 1.9.5.

First we're creating a new Zend Framework project using Zend_Tool on command line, by issuing the command zf create project zfunit in the workspace directory I use to share my VMWare instance with my workstation.

Ok, we now have a default Zend Framework application running.

We're not going to build a complete application here, but just showing how you can start unit testing your Zend Framework project, so you can implement unit tests on your own applications.

First we need to modify the phpunit.xml file so we can use it as our unit testing configuration.

<directory>./directory>

testsuite>

<directory suffix=".php">../library/directory>

<directory suffix=".php">../application/directory>

<directory suffix=".phtml">../application/directory>

exclude>

whitelist>

filter>

<log type="coverage-html" target="./log/report" charset="UTF-8" yui="true"

highlight="true" lowUpperBound="50" highLowerBound="80"/>

logging>

phpunit>

As you see in the root node of our phpunit.xml file, we include the TestHelper script to aid us setting up the right testing environment. Of course, you can modify this file to fit your own application setup. This is my TestHelper script to set up my test environment, include paths and setting timezones.

// start output buffering

ob_start();

// set our app paths and environments

define('BASE_PATH', realpath(dirname(__FILE__) . '/../'));

define('APPLICATION_PATH', BASE_PATH . '/application');

define('APPLICATION_ENV', 'testing');

// Include path

set_include_path(

'.'

. PATH_SEPARATOR . BASE_PATH . '/library'

. PATH_SEPARATOR . get_include_path()

);

// Set the default timezone !!!

date_default_timezone_set('Europe/Brussels');

// We wanna catch all errors en strict warnings

error_reporting(E_ALL|E_STRICT);

require_once 'ControllerTestCase.php';

We create a custom ControllerTestCase that we can extend in all our controller test cases. This proves to be the most convenient way to handle the setup and teardown of the Zend Framework architecture.

require_once 'Zend/Application.php';

require_once 'Zend/Test/PHPUnit/ControllerTestCase.php';

abstract class ControllerTestCase extends Zend_Test_PHPUnit_ControllerTestCase

{

public $application;

public function setUp()

{

$this->application = new Zend_Application(

APPLICATION_ENV,

APPLICATION_PATH . '/configs/application.ini'

);

$this->bootstrap = array($this, 'appBootstrap');

parent::setUp();

}

public function appBootstrap()

{

$this->application->bootstrap();

}

And finally we create our first test on the default IndexController.

require_once realpath(dirname(__FILE__) . '/../../ControllerTestCase.php');

class IndexControllerTest extends ControllerTestCase

{

public function testCallingRootTriggersIndex()

{

$this->dispatch('/');

$this->assertController('index');

$this->assertAction('index');

}

public function testCallingBogusTriggersError()

{

$this->dispatch('/bogus');

$this->assertController('error');

$this->assertAction('error');

$this->assertResponseCode(404);

}

Running phpunit from commandline will tell you that your assertions succeeded and all is a go.

All green, assertions succeeded and report is generated.

I've setup my test environment that directory log/report is aliased by /report, so I can view the code coverage reports (requires XDebug).
The following code coverage report is the result.

As you can see, with just a minimal effort you've set up your Zend Framework application to be unit tested. So now you don't have any more excuses to leave your applications untested.

Since I don't have all the knowledge, I would like to thank Matthew Weier O' Phinney and Mathias Geat for sharing their knowledge on the subject. Thanks guys !

ZendCon 2009 Review

2009-10-25T07:51:00.000+01:00

If you're involved with PHP and you haven't heard of ZendCon before, you have been around the wrong croud!

The past week was reserved for the biggest PHP event of the year bringing you the best of the best the open-source and commercial world have to offer developers and businesses. And it rocked, big time!

With a full day of tutorials and three days of top-notch presentations given by people that make things happen in the PHP ecosystem, you got a real bargain for your money.

Besides these brain overloading sessions, Keith Casey, king of the uncon sessions, hand-picked the best sessions rated and presented by the audience itself. And even though the main conference was mindblowing, Keith made sure that people had a hard time choosing between main tracks and uncon sessions. Job well done Keith !!!

I was scheduled for three uncon sessions myself.

On Monday I talked about unit testing with PHPUnit and Zend Framework.

Php Unit With Zend Framework Zendcon09

View more presentations from Michelangelo van Dam.

On Tuesday Anna Filina, Bradley Holt and I talked about the role of PHP user groups and provided tips on (re)starting a user group, how to get involved with open-sourse projects and how to get sponsorships from local businesses and big enterprises. I made a recording of the session, but sound quality is poor, so I need more work on it to improve it. Stay tuned for more.

On the third day I was scheduled for my "SPL, not a bridge too far" session but I (and others) were a bit too late for such an early schedule due to the fact that Microsoft was giving an awesome party downtown San Francisco to celebrate the release of Windows 7.
Because we parked our rental car in a car park that closed around midnight, we were happy we could join other conference attendees and speakers on a party bus bringing us back to the hotel where we arrived at about 4am.

Conversations on community stuff with Keith Casey and Anna Filina kept us out of bed until way passed 5am leading up to the fact that I arrived late at my own session scheduled for 8am.
Luckily no one was there to miss me, but still… ariving late at your own gig is so 80's.

For those that couldn't make it to San Jose, you could follow along on IRC channel #zendcon, Twitter and Flickr. Even some Google Waves and Youtube movies were spotted here and there.

A few good things were braught to the attention of all attendees.

people and businesses should get more involved in contributing back to the open source projects they use themselves
there is no best framework out there so look for the one that best fit your needs
there's a lot of talent out there that's not supported enough by the company they work for to become educated on advanced topics or even get certified
beware of the weierophinney !!!

Conclusion

ZendCon proved to be the top-notch PHP conference of this year, seeing lots of old and new friends giving the best of themselves. Like the German PHPcc who gave an awesome amount of tutorial, main and uncon sessions, my dear friend and genius Matthew Weier O' Phinney who was more on stage then amongst the audience and of course Keith Casey, who ruled the uncon sessions in a magnificent way.
But to be honnest, ZendCon would not exist without the community that gave us PHP, Zend along with S&S for organizing this event and the sponors that pushed the ticket prizes down to an affordable level. Thank you all and see you next year at ZendCon10.

Spl Not A Bridge Too Far phpNW09

2009-10-10T15:22:00.002+02:00

This morning I had the honor to speak at the PHP North West (phpNW09) conference in Manchester (UK) about SPL. It was almost a full room and it was wonderful to see and hear people being impressed what SPL can mean for them, so I believe it was a good session.

For those who attended my talk, you can leave your comments and feedback at http://joind.in/613 and be sure to rate the conference itself at http://joind.in/event/view/70.

Bughuntday: yes, you can!

2009-09-24T08:07:00.004+02:00

Last week Thursday the start was given to Zend Framework's Bughuntday and it turned out to be a huge success, as mentioned by Chief Architect Matthew Weier O' Phinney on Zend's DevZone website.

Over a hunderd bugs were squashed leading up to the release of Zend Framework 1.9.3.

What is Bughuntday ?
Bughuntday is actually a term to indicate that on a specific day (or days), lots of developers are focussing their attention to fix bugs, often reported by users in a bug tracking tool (like Jira, Mantis or Bugzilla).

Since lots of users have submitted issues and only a few developers have time to investigate them, extra help is always welcome to clear a backlog of reported issues.

So, each year a "Bughuntday" is scheduled to have many developers fix issues in a relative short timeframe.

You can help !
Fixing bugs for Zend Framework is a very good way to learn best coding practices or parts of the framework you're not familiar with.

Go over to the Zend Framework Issue Tracker and look for bugs that are still open.

If you already signed the Zend CLA, you're good to go. If you haven't done this, now is a good time to do so.

Get the latest revision from http://framework.zend.com/svn/framework/standard/trunk/, which includes the library, unit tests, external libraries and documentation.

In case of emergency
If you're stuck, or you have created a patch to fix an issue, head over to #zftalk.dev on IRC (freenode) where you can ask for help.

The Zend Framework Bughuntday is held each third Thursday and Friday of the month and each month prizes are given to the top 3 fixers.

If your company uses Zend Framework, see if you cannot make it a company thing. The quality improvement of Zend Framework will be a great benefit for your company as well.

Speaking at PHPNW09

2009-09-05T01:27:00.000+02:00

It's almost fall again and it's amazing to see how many great conferences are scheduled. Seems impossible to choose between great talks given by the best developers worldwide.

One of those great conferences is held in Manchester, UK. It's PHPNW09 with an awesome schedule listing well known and lesser known people from the international PHP community (like Stefan Koopmanschap, Derick Rethans, Lorna Mitchel, Rob Allen and many more). This year I'm on stage too talking about the Standard PHP Library or SPL.

Something that I really like about the PHP community is that we all help each other getting better at the things we do. After I gave my SPL talk at DPC 09 earlier this year, I got so many responses and pointers on the presenter rating site Joind.in which were very helpful improving this presentation.

So, if you have a day to spend on PHP, come and join us at PHP North West conference 2009. Prices are reasonable and flights are fairly cheap compared to the massive information overload you're about to absorb there.

Book review: Mastering phpMyAdmin 3.1

2009-08-15T12:54:00.000+02:00

A couple of weeks ago I received a book from PACKT Publishing titled "Mastering phpMyAdmin 3.1 for Effective MySQL Management " written by Marc Delisle, with the request if I could read it and write a review about it. Why not ? I haven't used phpMyAdmin in whole my career so I might as well read about the tool everyone around me is using. And since phpMyAdmin is also bundled with Zend Server, it can only benefit my day-to-day job.

On the front cover it states "Increase your MySQL productivity and control by discovering the real power of phpMyAdmin 3.1", so the book challenged me from the start. I have been using the MySQL command-line tool since forever so I was really curious about how this book could convince me to use phpMyAdmin from now on.

The first two chapters of this book are explaining what phpMyAdmin is all about and how you should install it, along with a very detailed security configuration part. A remarkable feature is that you can install it for multi-user hosting purposes, giving each user it's own MySQL toolset using just one installation.

Chapter 3 covers a very detailed explanation of each panel you see in the phpMyAdmin interface. Not only a mere statement that explains what each panel is used for, but also how you can modify this panel's behavior by modifying the configuration settings.

A hands-on example is covered in chapters 4, 5 and 6, where Marc takes you on a journey through all the steps of creating, inserting, browsing, modifying and removing tables and data. Although I was already familiar with MySQL's capabilities, I have to admit that by using a tool like phpMyAdmin your whole data management becomes more visible and gives you a certain amount of joy browsing through your data.

With MySQL on command line I could import/export my data and table structures in native SQL and XML, but with phpMyAdmin you can choose between 14 different export types. Although I believe that SQL will remain the main type used by many, it's good to know you have a tool available that can export data anyway you want.

Another cool feature I discovered by reading this book is that phpMyAdmin offers you the ability to manage relations between tables easily using the interface, but you can also create graphical relation diagrams that you can export into PDF.

With it's MySQL 5.0 and MySQL 5.1 support you also have the ability to manage the advanced MySQL toolset like triggers, stored procedures, functions and views. Having the ability to use these advanced MySQL capabilities in a graphical interface can only benefit it's usage amongst many developers.

But the best feature of phpMyAdmin is that you could have in-table MIME-type based transformations. So if you work often with BLOB data, you can now have it appear right in your interface as a download link or as a clickable thumbnail.

If you're new to phpMyAdmin or you just start using MySQL databases, this book gives you step-by-step instructions on how to use the interface to manage your data. But I think this book has even more value to the professional where this book is the perfect reference guide for all those advanced MySQL capabilities. I will certainly use phpMyAdmin more, having this book besides me to guide me the way.

Dutch PHP Conference 2009 wrapup

2009-06-17T17:11:00.000+02:00

A couple of days ago I came home from one of the best PHP conferences in the world, Dutch PHP Conference 2009 with again a very elite list of speakers.

Day 0: Tutorial Day

Thursday, June 11 was tutorial day. A whole day dedicated at learning new things by the greatest PHP minds in the world.

I attended the "Zend Framework Workshop" by Matthew Weier O' Phinney, Chief Architect at Zend Framework.

I went to see this tutorial session to see all the goodies that are put in Zend Framework 1.8 and to learn how to do stuff better. Great stuff like Zend_Tool, Zend_Application and other Zend Framework components are worth checking out.

As it appears, I have to look into the Zend_Acl adapter using a configuration file or an external source and contribute my solutions to the Zend Framework wiki.

Afterwards a Belgian delegation went down-town Amsterdam to have dinner at an Italian place and a drink afterwards at "Leidse Plein".

Day 1

Day one was a very hectic day for me since I was scheduled to speak at 10:30am. But we'll get there in a minute.

Opening keynotes

Before the opening keynote of Cal Evans, Director of PCE at Ibuildings, an awesome animated movie was shown to the public.

Cal Evans talked about what everyone could expect at the conference, what the rules of engagement were and what tags to use during the conference (a very important note).

Andrei Zmievski opened the conference officially talking about "PHP: people, code and ideas". Too bad I had to flee the scene half way the presentation to set up my gear for my own talk about SPL.

Morning Sessions

I hosted a talk called "SPL, not a bridge too far" where I discussed on a low level (according to some, a bit too low) the funky features SPL brings to the table. And looking at the comments left on joind.in I actually got people interested in using SPL in their future development projects.
Too bad I cut it short, like most people mentioned, because there's a whole lot to tell about SPL. Thanks everyone for you feedback, I will definitely keep it mind to make my presentation better.

Ben Ramsey showed us that "Grokking the REST architectural style" is worth thinking about when dealing with REST web services. He also talked about ATOM as a protocol, and he really got me interested in it to find out more. Thanks Ben, it was awesome.

Afternoon Sessions

Matthew Weier O' Phinney impressed us all again with another talk about "Contribute" and what we developers could do to make a difference.
For everyone involved in open-source projects, a must see presentation and again lots of kudos to Matthew for bringing this point to the attention of the masses.

Unfortunately I missed Stefan Esser's talk about "Secure Programming with the Zend Framework" and I'm now waiting for the slides to appear online.

Closing talk of the day was Christian Wenz with "Web Accessibility - A Primer" about the directives to make your web applications more accessible. Although I do appreciate the topic, Christian listed many items straight from the W3C Website and read them out to the public.
A good topic but not much new stuff in it, if you've checked out the W3C Website already.

Speakers Dinner

In the evening the DPC crew had organized a speakers dinner, where all the great minds joined together enjoying talking with each other about PHP and other non-PHP related things.

After the dinner, a social event was held at the tiki bar Strand Zuid.

Back at the hotel I was engaged in a few conversations about Zend Framework and PHP in general. Although I enjoyed those conversations, ending up in bed at around 3:30am was certainly not good for getting up in time the following day.

Day 2

Still in a sleepy state of mind, I headed out to the conference for day 2 missing the opening keynote by Owen Byrne on "Digg: The first two years". But the coffee break afterwards I certainly attended.

Morning Sessions

Eli White introduced us to the wonderful world of scalable websites with his presentation "Habits of Highly Scalable Web Applications" and believe me, there are a few things that you might want to investigate further !

Then our dear friend, icon of the Dutch and Belgian PHPWomen and most definitely a great host Juliette Reinders Folmer (@jrf_nl) gave by far the best presentation at DPC titled "Everything you always wanted to know about UTF-8 (but never dared to ask)" where she takes you down the road of UTF-8 encoding issues and looks ahead of the nifty features PHP 6 brings to the table with it's Unicode support.

Since everyone rated this talk as "best talk ever", I won't be surprised to see it on the ZendCon 09 scedule (hint for @EliW) or on other major PHP conferences worldwide.

Afternoon sessions

After lunch I went to see Rob Allen to learn more about "Caching for Performance", but right in the middle of this very interesting session I had to bail because a mix-up with the hotel had taken place. Believing my room was booked until the 14^th, I was surprised to hear I had to clean up my room. So I was rushing back to the hotel to get all my stuff.

When I returned, Lorenzo Alberton was already rounding up his talk about "Trees in the Database: Advanced Data Structures". Too bad, since I believe it was also a very good and interesting session.

Closing Keynote: The Cal & Ivo Show

Rounding up the conference, Cal Evans and Ivo Jansch were giving sit-in session where they invited 3 guests on stage to talk about PHP: Andrei Zmievski, Lorna Mitchel and Paul Reinheimer.

Although the discussions were very interesting, most of the attention was drawn to the big screen behind them where tweets and photos were shown that were taken, uploaded and tagged during the conference.

Afterwards drinks were served for attendees, but I had to catch my train ride back home so I couldn't stay to enjoy the good vibes DPC audience was generating, but even in my train I could feel the air buzzing PHP.

Conclusion

Ibuildings has done it again, DPC 2009 will certainly go in the history books as being the best conference ever !

Many thanks to the Cal, Ivo and all organizers, the Ibuildings Design team (for making an awesome video and creating very cool speaker avatars) and to the sponsors of the event (Zend Technologies, Inc., Oracle, IBM and Microsoft) for their participation in this event and lowering the price of the tickets.

If you missed the event, or you want to catch up on great talks and tweets about the talks, I've provided here a small list of important sources where you can find more about DPC 2009:

php|tek 09 - Overview of an awesome conference

2009-05-28T12:03:00.003+02:00

For those who just returned from outer-space, last week was PHP|Tek 09 in Chicago, IL, USA. By far the most intensive PHP conference ever, organized by PHP|Architect, the true PHP magazine. I give here my experiences as I have recorded them during these very intense days.

Tuesday, May 19
As it is common with many (PHP) conferences, the first day is often a tutorial day, where you get 3 hours of high quality tutorials given by the great minds within the PHP community.

I attended Ed Finkler's session on MVC development in PHP where he talked about the best practices on implementing MVC and what the differences were between several frameworks.

After lunch I headed out to PHP Code Review given by Stefan Priebsch, Sebastian Bergmann and Arne Blankerts, all three co-founders of the PHP Consulting Company.

Wednesday, May 20
Andrei Zmievski opened the conference with a very impressive key note about PHP 6 (after he could free himself being tied up in a dark room by Marco Tabini).

Cal Evans impressed us about using Zend Framework for CLI development explaining clearly how you can use the power of Zend Framework to kick of applications on your command line. Go Cal !

During the day I missed a couple of sessions because I had very interesting talks with other people there at the conference, but I managed to be back in time to watch Elizabeth M. Smith talk about SPL to the Rescue (a topic that I like so much, I'm going to talk about it myself at the Dutch PHP Conference). She did an amazing job explaining why one should use SPL in the first place and even got people motivated to help improve today's documentation of SPL on php.net website.

If you want to do unit testing on your (PHP) code, you must ensure you code is testable. Sebastian Bergmann has given a great session on Untestable Code, or which are the things you need to think about when writing code so it can be tested.

In the evening I was hosting an uncon session about PHPUnit testing and Zend_Test where I described the various ways to optimize your tests, how to test databases and how to test your Zend Framework application.

Thursday, May 21
If you wanted to know what's included in the PHP 5.3 releases, you should have attended Sara Golemon's session PHP 5.3 - Hot or Not ? where she actually gives you more insight great features that have been added to the PHP 5.3 releases, besides namepsaces.

For all those new to Linux, check out Linux-Fu given by Lorna Mitchel where you get an explenation about the tools that are really useful on your command line. Also good if you don't use a mouse.

Eli White has given us more insight in the fundamentals of software development with his session The Knight Rider Methodology to Software Development where he's comparing situations that Michael Knight and KIT were in with situations software developers come accross.

Lorna Mitchel and Stefan Koopmanschap gave us more insight into the community behind php with their session A Guide to Using and Understanding the Community. Since this talk was so great, they repeated this session on Friday for recording purposes.

During the uncon sessions I was hosting a round table discussion about PHP user groups and what can be done to draw more attention to these user groups, how to start up with one or how to restart a dorment user group. Getting lots of feedback, I'm going to add all this information into a presentation that can be called the 101 on php user groups. Also keep an eye out for Clark Everetts website about this session, because he has written down lots of stuff.

Friday, May 22
Closing keynote was provided by Terry Chay, the guru of explicit presentations. Since you know you're in for a treat, people were counting Terry's f-bombs while enjoying his talk. A video recording was made so you can count f-bombs and enjoy the show yourself as well.

Immediately afterwards I attended an uncon session from Paul M. Jones about Benchmarking PHP Applications where Paul made a great comparison between frameworks and franchising your business. Awesome presentation and I'm looking forward attending more sessions of Paul.

Closing the conference, I hosted my last uncon session about implementing Continuous Integration step-by-step, where I discussed the common situations all developers have seen leading towards an automated integration system using the tools best fitted to do the job.

Final notes on this conference
This was the best PHP conference ever, where talks were given targeting intermediate to high levelo developers, awesome catering and lots of fun after-hours. I want to express my great gratitude to all that were responsible organizing this event and I'm looking forward attending next conferences.

If you weren't there, I want to suggest attending next year's conference. You learn so much in the mids of everyone who's involved with PHP core, PHP applications or PHP services. If you can't get an answer there, don't bother become a PHP developer.

PHP|Tek 09 - Uncon session: PHPUnit testing to Zend_Test

2009-05-21T20:34:00.002+02:00

At the first day of PHP|Tek 09 I presented a session on Unit testing using PHPUnit, starting off with a simple example to explain unit testing and ending with testing a Zend Framework application using the application bootstrap.

If you attended this session, I'd love to hear from you at http://joind.in/442

PHP Test Fest 2009

2009-05-11T00:50:00.000+02:00

For those who haven't heard about it, last Saturday was PHP Test Fest 2009, and here in Belgium it was organized by PHPBelgium at the new Combell location in Ghent.

We decided to test the SQLite3 extension, and we also had two people writing tests for LDAP. With a nice end result of 24 tests written for SQLite3 and 9 for LDAP, we are very pleased with the result since only 9 people attended our event.

Our mentor Felix De Vliegher had given us a very clear instructions and apparently most attendees already had seen my (and other people's) slides on slideshare.net. See the pictures of those great moments on flicr.com.

All attendees did share a few common quotes afterwards:

"I learned so much here"
"Next year I come back"
"Shame on those who didn't come today"

I would like to express my gratitude for the PHP QA Team for organizing this event, to Combell for facilitating this event and providing us very nice sandwiches and drinks and to Ibuildings for providing us a USB stick where we can store our libs and tests on.

If I do get some "spare" time, I surely will keep on writing tests for the PHP core, because it is so important to ensure good code coverage on each and every PHP component.

In the time being, do check out the code coverage reports for PHP 5_3 and see for yourself that there's still a lot of work to be done to get everything in the green. So step up and help PHP helping you.

Speaker at Dutch PHP Conference 2009

2009-04-09T15:36:00.000+02:00

I'm happy to announce I'll be presenting a talk at the Dutch PHP Conference 2009 in Amsterdam, a yearly PHP conference organized by Ibuildings - The PHP Professionals. This conference is mainly for PHP developers, businesses, governments and educational institutes. But everyone is welcome to experience the warm, fuzzy and very social aspects of PHP and it's community.

My presentation "SPL, not a bridge too far" is actually an attempt to promote the usage of the Standard PHP Library. SPL provides so many features for iteration and array handling, but is not used or looked at by many developers. My goal is to show with examples that SPL can be a very powerful tool, and thus promoting the usage of SPL.

Dutch PHP Conference 2009 is the place to be this year for everyone who's involved with PHP, and the list of speakers is awesome: Matthew Weier O'Phinney, Derick Rethans, Scot MacVicar, Eli White, Juliette Reinders Folmer and Maarten Balliauw (to name a few).

Ticket sale is now open. Get a € 100 early bird discount on a three-day ticket or € 55 on a ticket for Tutorial Day only, if you order your tickets before April 30, 2009. Go quickly to the registration page and get yourself a seat for the hottest PHP conference in Europe.

When mobile services are failing...

2009-02-23T15:17:00.000+01:00

The story
About 3 months ago I switched from mobile provider Proximus to it's competitor Mobistar because of lower rates and special deals for self employed people. Because we were close to New Year, I asked politely to make the transfer after New Year.

It all started on December 24 when all of a sudden, my old provider dropped the connection. They received the paper declaring I was switching providers. So, as instructed I switched SIM cards and I was now Mobistar customer.

But although I was able to make outgoing calls, I couldn't get incoming calls or messages. Being the day before Christmas, this is a major issue. Calling the service desk, didn't really provided me with a solution since they blamed Proximus for not transferring my number correctly.
I then called my dedicated agent, but he was already packing for his Christmas holidays and not having time to figure it all out. So I was unreachable until December 27.

All services were allright until December 31st, when I received my first "No service..." message. Again calling Mobistar service desk was a failure, they referred me to a local Mobistar shop to have my SIM-card replaced. So I did, replaced my SIM-card and had to wait for activation, which actually occured on January 3rd 2009. Since then, things started to look brighter and services were up-and-running.

But on February 16, I noticed again a "No service..." message on my iPhone. When I called the Mobistar help desk, all they did was referring me to a local Mobistar shop saying something was wrong with my SIM-card. I've come to think of it as being a default answer for all issues.

Again, today I experience the same issue with my iPhone. Again a "No service..." on top of my screen. So, while visiting Mechelen city center for lunch, I visited the Mobistar shop and had my SIM-card replaced again. Having to wait about half an hour, and all services should be up-and-running again.

Waiting for more then an hour, I first checked if my iPhone wasn't broken by using a SIM-card of another provider (Vodafone NL) before deciding to give Mobistar support desk a call. And now I know the true story behind all misery:

Mobistar is having issues with their provisioning system, so new SIM-card activations cannot be processed correctly (I shall have to wait)
Mobistar is experiencing network issues in my area (Mechelen North) and are working hard to solve it
Mobistar does not want people to read about it, so they only tell this to people who call in (very convenient when you're mobile services are out)
Mobistar does not inform their shops either of failures, since the Mobistar shop I visited checked for systems, services or network failures.

The punch
The Internet is a great way to communicate to your customers. You can mention successes to the whole world... but you can also provide information to your customers for moments when things aren't going as they are supposed to.

Mobistar could have made me (and other customers) happy if we were able to check if services were down or not working at all. This would leave us at least with an explenation of why our service is unavailable so we could inform the people who are now trying to contact us and getting a system error.

Mobistar, if you care to read my post here, talk to Cal Evans about using internet services like Twitter as communication tools for your company. Your customers are using it to mention your failures as well.

Also, inform your customers. It's not difficult to set up a "Network status" page where you integrate you NOC information. If still in doubt, give me a call... I make you a special offer.

And one last thing: tell your call center agents not to blame others (it's their fault), because I'm a customer of Mobistar and how you internally run things is not my business. I'm only interested in when my service is up-and-running again.

Feedburner move to Google error

2009-02-23T12:06:00.001+01:00

This morning I checked my feedburner stats and I got a message I should move my feeds over to Google, and so I did.

I should have read Chris Shiflett's blog post first to prevent my feeds spamming the entire aggregated internet, in particular Planet-PHP.

So, I want to apologize to everyone for my massive spam on the various aggregation sites and a hint to Google: make sure you don't spam the internet while moving stuff from one place to another.

Fosdem 2009 in review

2009-02-11T14:47:00.145+01:00

Last weekend I was at FOSDEM'09, Free and Open-Source Developers European Meeting, in Brussels (Belgium). Together with co-founder Felix De Vliegher and co-organizer Patrick Allaert we were promoting the mission of PHPBelgium, the largest PHP user group in Belgium.

Besides promoting PHP and the activities of the user group, we also promoted phpwomen.org, an international organization for women involved in PHP development. Men are also welcome there.

On days like these, we're a central point for information and people used the opportunity to ask us a lot of questions regarding PHP. Here is a top 5 of most asked questions:

1. Where can I/our company turn to for advanced PHP training courses ?
I believe Ibuildings, the PHP professionals, located in the Netherlands and UK, are the best sources to turn to regarding training courses for advanced PHP and certification.

Ibuildings provides standard PHP training courses, including courses from php|architect, but can also provide custom training courses that meet the requirements of your company needs. Training courses are given by Zend Certified Engineers (ZCE's) with years of hands-on experience in complex PHP projects. More information can be found at http://ibuildings.com/technology/training.

2. Is there a certification program for PHP developers (like for Java, .Net, ...) ?
Yes, there is. Zend Technologies, Inc. has two sorts of certifications: Zend Certified Engineer (ZCE) for PHP developers and Zend Framework Certified Engineer for Zend Framework developers.
Training courses are provided by Zend Partners or by Ibuildings in the Netherlands and UK.

3. Is PHP enterprise ready ?
Yes, PHP is enterprise ready. As of PHP 5.0 the language is object oriented, scalable and available on many platforms (Linux, Microsoft Windows 2008 Server and IIS7, IBM's i5 Series, ...).

Especially now with the credit crunch and the unclear (financial) future for many industries PHP offers a lower budget solution for many web based application needs.

Professional PHP services and consulting for enterprises and governements are provided by companies like Ibuildings, AUSY, OmniTi, and many more.

4. I'm from ..., is there a PHP user group in my neighborhood ?
Well, it's hard for us to know each and every PHP user group in the world, so I suggest to turn to Google, Yahoo or Live Search to locate a PHP user group in your area. Usually "php user group " would do the trick.

5. Where can I get more information about PHP ?
There are many great sites and blog posts on the internet about PHP and is thus impossible to list all of them here.

A few good resources to start with are:

www.php.net (the official site for PHP)
www.zend.com (the site of Zend Technologies, Inc.)
www.planet-php.net (aggregation of very interesting blogs that cover PHP)
www.phpdeveloper.org (php news site and reference for every PHP developer)
devzone.zend.com (php articles)

Killer iPhone app from Apple: Keynote Remote

iTunes Appstore for iPhone and iPod Touch has a numerous list of great applications, but recently I discovered one that really rocks my world: Keynote Remote.

When giving presentations I used to have a separate pointing device that I could use to move through the slides, but now with Keynote Remote I can see what is up the screen having my speaker notes right there with me. Flip the display in a horizontal position, I can see my current slide and the next one.

Fig. 2: Current slide with next slide display.

This way I can move around the floor while giving presentations without having to stay behind my laptop to see what's next. This is especially good when you're co-presenting something, because now you can see the notes of your fellow speakers as well.

Requirements

You need to have Keynote '09 which is part of the new iWork '09 where you can set up your iPhone or iPod Touch for connecting with the computer.
You need to have a wifi network where both the Keynote computer and the iPhone/iPod Touch are on.

Keynote Remote costs $ 0.99 at the iTunes Appstore.

Mapping Seven Things

2009-01-05T09:32:00.000+01:00

Trying to get a bit of overview of all people who have put up their "Seven Things" list, I created a little map that shows who tagged who with an overview of the most tagged persons.

Check out the Seven Things map at http://in2it.be/whotaggedwho.php.

Seven Things - Tagged by Rob Allen

2009-01-03T15:04:00.005+01:00

I was surprised that I made it to the Seven Things thread started by Tony Bibbs, but Rob Allen was so kind to "tag" me and now it's my honor to find seven more victims.

Seven Things you might not know about me:

When I was 16, I had a private pilot license (PPL) learned at the Airport of Antwerp. The first year I managed to have enough flying hours to keep my permit but the second year I just couldn't find time to have the minimum required hours to keep my permit. Looking back at this moment in time, I do find it sad I didn't made the effort in maintaining this.
I graduated high-school as an accountant and had a job as a junior accountant at the Benelux head office of Century21, but after one month I was already convinced being an accountant was something I didn't wanted to do for the rest of my life. And never spoke of this part in my life again.
I never finished college. I was studying IT at the "Hogeschool Antwerpen" and after college hours I worked at the customer care center of an European ISP called World Online (no longer exists). When doing my second year IT they offered me a job as developer and I accepted the offer.
I met my wife during a LAN party at Telenet (Belgian Telco), where I was working as an in-house developer and my wife was on her last day as security guard (student job).
I'm Dutch, although I'm living in Belgium.
My wife told me we were pregnant on the last evening of ZendCon07 and I celebrated this news in a StarBucks shop just around the corner of the Motel6 I was staying at.
Our son was born on Father's day being the best gift a dad could wish for.

Now it's my turn to tag people:

Jay Pipes, a wonderful guy I met at ZendCon08 showing us there's a whole lot more stuff MySQL has to offer.
Maarten Balliauw, a great PHP/.NET developer who's career I've been following for several years now but only met personally about a month ago.
Patrick Allaert, co-manager of PHPBelgium and a great mind within the open-source community.
~~Matthew Turland, whom I've met at ZendCon07 and again at ZendCon08 who's given me great hints and tips with his podcast on site scraping and his blog.~~ Already tagged by Keith Casey, Matthew Weier O' Phinney, Rob Allen and Me.
Damien Seguy, the father of elePHPant and founder of nexen.net.
Christian Flickinger, the awsome dude I met at ZendCon07/08 who always knows how to turn things into a lot of fun.
Nick Belhomme, a Belgian PHP developer who first contacted me asking about doing PHP on a freelance base and now becoming a dear friend.
Sara Golemon, PHP guru at Yahoo! and who I've met also at ZendCon07/08.

For my tagged victimes, do follow the following rules:

Link your original tagger(s), and list these rules on your blog.
Share seven facts about yourself in the post - some random, some wierd.
Tag seven people at the end of your post by leaving their names and the links to their blogs.
Let them know they’ve been tagged by leaving a comment on their blogs and/or Twitter.

Looking back to 2008

2009-01-01T14:24:00.009+01:00

First I want to wish everyone all the best for 2009 ! 2008 has been a very wonderful year and makes us looking positive to the future. To cope with the challenges we have to face in 2009, it doesn't hurt looking back to the past year and see where we can improve or act differently.

Let me go over a few keywords that had importance in 2008.

PHPBelgium
2008 was the year both Felix De Vliegher and I founded PHPBelgium, a PHP user group for PHP enthusiasts in Belgium. We had a slow start, but as the months passed by the popularity and importance of PHPBelgium grew. Not only for PHP enthusiasts but also for companies as Microsoft, O'Reilly, Ibuildings and AUSY. In October, Patrick Allaert joined our management team.

Besides providing best practices and presenting advanced programming topics, we also try to do as much as possible for the community by giving away elePHPants, books and tickets to PHP conferences (like ZendCon, php|works and phpnw).

phpGG
Besides a good start up for PHPBelgium, the Dutch counterpart phpGG had also a very successful re-start in 2008. With more meetings, activities and combining forces with PHPBelgium to organize two very succesful theme-days (PHP Test Fest and BugHuntDay), they now are the most important PHP user group in the Netherlands.

Baby Xander
For me personally, 2008 was the best year ever with the birth of our son Xander. In the past 6 months he has grown into a very curious, enthusiastic and happy baby boy. Both my wife and I enjoy each day we can spend with him, seeing him discovering new things, learning new stuff and becoming very familiar with his surroundings. It's like watching a million years of evolution taking place in only a few months.

Ibuildings
2008 is also the year for Ibuildings, becoming Europe's leading PHP professional services company. They first started in 1999 in Flushing, the Netherlands and extended their reach to the UK at the end of 2007. They are internationally credited as being an expert in PHP and related technologies, raising the bar on professional services and quality assurance. To quote the international PHP community: "Ibuildings is the new black", and I have to admit it's true.

Job Changes
I think 2008 is also the year where a lot of people changed jobs, including myself. But I think the most thrilling news was that Cal Evans changed shirts, from Zend to Ibuildings.

Namespaces
PHP 5.3 is about to reach its final stadium, but there was a HOT discussion for it's namespace implementation. I didn't follow the whole discussion, so I'm only reflecting here what the buzz was on almost all PHP channels.

Yes, we can !
2008 is also the year that an African-American won the presidential elections in the US. Although it has nothing to do with PHP, it sure is worth mentioning it here in my 2008 overview.

Obama's quote "Yes, we can !" does not only reflect on his mission in the White House but also for all PHP developers in the world. "Yes, we can !" will also be our default answer in regards to web application development, rich internet applications, social community projects and so much more. Yes, we can !

Zend Framework
I think it's fair to say that 2008 was also the year for Zend Framework, with over 10 million downloads (and counting), becoming the leading framework for enterprise web application development (and also large scale websites).

With the introduction of a certification exam for Zend Framework (ZFCE), Zend has enormously boosted the professional level of this powerful framework and with initiatives like BugHuntDay, the community involvement has increased a lot.

Also books like "PHP|Architect's Guide to programming with Zend Framework" by Cal Evans and "Zend Framework in Action" by Rob Allan, have boosted Zend Framework's popularity. And of course the many blogs and presentations that are too numerous to mention here have added their share to it's popularity.

Credit Crunch
We cannot neglect the fact that we're right in the middle of a financial crisis, refered to as the "credit crunch". I wish I could say it was something of 2008, but it will have effects in 2009 as well.

The credit crunch has effects in many industries, including the IT industry. Many large IT companies are faced with layoffs and this will continue to be a reality in 2009 as well.

But given the nature of PHP, being an open-source programming language, with a non-expensive nature and a rapid deployment history, this financial crisis might become a lucrative moment for PHP development in general. This thought is also shared by Ivo Jansch, CTO of Ibuildings who mentioned it in a blog post reflecting 2008.

Thank you !
Of course, 2008 has been a wonderful year for me, mostly because of you. Giving me constructive comments on my blog posts, meeting me at conferences and congratulating me on presentations that I share on slideshare.com. So, thank you for all the love !!!

Book review: Zend Studio for Eclipse - Developer's Guide

2008-12-28T21:00:00.001+01:00

Book: Zend Studio for Eclipse, Developer's Guide
Authors: Peter MacIntyre and Ian Morse
Publisher: Addison-Wesley Pearson Education

Description
Zend Studio for Eclipse, Developer's Guide from Addison-Wesley Pearson Education is a guide to Zend Studio for Eclipse (ZSE) for intermediate to advanced developers.

The book has 18 chapters, with the first 16 covering the different views and preference settings for each specific task. The first 5 chapters are explaining basically the layout of the Eclipse working environment, with a focus on how to modify these views for your own benefit. The last 2 chapters are devoted to working out an example application using ZSE with Zend Framework.

Personal opinion
This book is in my opinion a beginner's guide into using ZSE, aiming at PHP developers that have a knowledge of general concepts like versioning, debugging and refactoring. I personally was hoping to see advanced settings to tune the IDE into a powerful developer's tool, but it was merely a basic explanation with the correct terminology for a product that I've been using well over two years now (yes, I was also beta-tester for it).

Conclusion
If you're new to Eclipse in general and specifically Zend Studio for Eclipse, I believe this book is going to be a valuable asset. It will not only give you insight in how the Eclipse IDE works, but it shows you also the possibilities to turn this into a very powerful tool for building PHP applications.

But if you're already a ZSE veteran I'd have to advice not to buy this book since it has no extra value then to explain the settings/views you've been using all along.

Successful 6th annual FeWeb Conference

2008-12-11T11:14:00.002+01:00

Yesterday evening I attended the 6th annual FeWeb Conference in Edegem, Belgium with my Ibuidlings collegues Ivo Jansch, Harrie Verveer and Bjorn de Haan. Also fellow co-founder of PHPBelgium and soon-to-be collegue Felix De Vliegher was there. According to their own blog over 200 persons attended this year's event that had several short tech-tracks and 3 key notes.

I first attended the "Battle Flash vs AJAX" between Peter Elst and Peter-Paul Koch and although it wasn't really a battle, it became clear that there's much to say about RIA's in general.
You can find the presentation on slideshare (where else ?).

After the break FeWeb chairman Marc Mestdagh announced the planning for 2009, followed by handing out awards to the FeWeb Quality Label winnars (Webdoos, 2MPact and Media Mates).

Wim Roggeman of the Belgian Internet Service Providers Association (ISPA) talked about copyrights and the new social infrastructure of the Internet today. Nice to see that he's using the succesful computer gaming industry as a showcase how the music industry should work today.

Final keynote was given by Luc Beirens, chief of police for the Federal Computer Crime Unit (FCCU), where he gave an interesting talk about e-crime today and how cyber criminals use the same networks as we to operate (except they're not as visible). A few interesting facts he mentioned were:

India has now "cyber soliders"
There are still many security issues related to input validation and filtering
Identity theft will become a serious threat
There's a need for a global jurisdiction to fight off cyber crime
End users should have some responsibilities as well (ref. driver's license)

Twitter was heavily used during the sessions, making it possible for people who couldn't attend to have an idea what they were missing (#feweb).

Of course the drinks and social event were also a highlight of the evening, talking with so many people and discussing ways to promote PHP in Belgium. Through this post I wish to thank everyone for their input, we will work something out.

Many thanks for the organization of FeWeb Conference 2008 (and the sponsors Combell and bSeen).

FeWeb is an organization for web developers in Belgium that provides information about legal concequences linked to the job as "web developer", interacts with the government and the industry to advocate the role of the industry and issues a quality label for Belgian web development agencies.

Belgacom - Proximus roaming failure

2008-12-05T12:36:00.000+01:00

In this day and age people have a tendency to check the internet first before calling tech support, but apparently some big companies don't get that.

I'm in the Netherlands now and since this morning my mobile phone has no service. So I checked the websites of both Proximus (my cellular provider), Belgacom (it's mother company) and Vodafone (it's partner) to see if there's a problem with their network or services. Nothing was mentioned, nor was there any reference that anything was wrong.
So I spend the whole morning calling to tech support of Proximus to figure out why I don't have any service.

First I was kept on hold for about an hour. In my second attempt I could finally was ablte to talk with a tech support agent telling me the whole roaming service was down and all people abroad weren't able to connect to the cellular network.

This was a general system failure that already lasted several hours but the company didn't even bothered to mention this on the website, having it's customers calling tech support from abroad (paying huge international phone call tarifs) just to find there's a problem at the company.

Dear Proximus, put this kind of failures on your homepage ! This saves a lot of stress, and gives your customers the posibility to provide alternatives to contact friends, family or customers.
