This is actually just a modification from JavaScript Round To Nearest Number by Talk in Code. Instead of getting the nearest digit, we will actually get the rounding to the next nearest number.

function roundNextNearest(num, acc) {
    if ( acc < 0 ) {
        return Math.round(num*acc)/acc;
    } else {
        var value = Math.round(num/acc)*acc;
        if (value < num) {
            value += acc;
        }
        return value;
}

Let’s make the web faster

Some people might find WordPress’s get_option and update_option function helpful over filesystem based configuration where you don’t want user to frequently update the configuration files. Today let me show you how we can utilize the same functionality in CodeIgniter using Option Library.

Requirements & Basic Informations

Before we start, let lay out some fact about Option Library:

• is based and developed on CodeIgniter 1.7.1, it might work with previous version but please do test it out first.
• use CodeIgniter build-in Database Class without ActiveRecord so there no problem if you disabled it.
• we cache the result on every pageview, Option Library query the table and cached it in an Array which mean Option Library doesn’t overhaul your database.

Getting Started

To use the Option library, you have to checkout a copy of latest Codenitive or grab the following files:

• http://myci.googlecode.com/svn/trunk/system/application/libraries/Option.php
• http://myci.googlecode.com/svn/trunk/system/application/config/application.php

Database

Before you can configure Option Library let first create a new table:

CREATE TABLE `options` (
 `id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
 `name` VARCHAR( 255 ) NOT NULL ,
 `value` TEXT NOT NULL
) ENGINE = MYISAM ;

Configuration

Open system/application/config/application.php and go to line 35. You need to enable Option Library (allowing CodeIgniter the fetch from your option table) and identify the table schema based on the table you just created above.

$config['option']['enable'] = TRUE;
$config['option']['table'] = 'options';
$config['option']['attribute'] = 'name';
$config['option']['value'] = 'value';

Using the Option Library

This is just a simple example how you use the library.

class Main extends Controller
{
    function __construct()
    {
        parent::Controller();
        $this->load->library('option');
    }
    function index()
    {
        // to retrieve a value
        echo $this->option->get('copyright');

        // to set a new value
        $this->option->update('copyright', '© 2009 Codenitive.');
    }
}

This is a collection of guide how to install Apache Httpd Web Server complete with latest PHP (as Apache mod), MySQL for Ubuntu. As a bonus, I even through in an additional guide to install PHPMyAdmin. Please do note that most of this guide can be found elsewhere which is listed at the bottom of the guide.

Getting Started

I’m sure everyone here is familiar on how to use Terminal which is available from:

Applications > Accessories > Terminal

Install Apache Httpd Web Server

To install Apache, type the following command into your Terminal:

> sudo apt-get install apache2

Testing Apache

Paste the following command into your Terminal

> sudo /etc/init.d/apache2 start

Then open http://localhost/ or http://127.0.0.1 from your web browser. At first run, you would probably see a directory listing or a HTML page with a text saying “It’s Work“.

To browse the file please navigate to the following folder

> cd /var/www/

Install PHP

Similar to Apache, all you need to do is type the following command in your Terminal:

> sudo apt-get install php5 libapache2-mod-php5

After the installation is complete, do restart your Apache Http Web Server.

> sudo /etc/init.d/apache2 start

This allow PHP to be include as Apache mod.

Testing PHP

A simple way to test your PHP is via phpinfo() function which display all related configuration of your PHP. To do so type the following command in your Terminal.

> sudo gedit /var/www/phpinfo.php

This will open gEdit text editor which you will type in

<?php phpinfo(); ?>

Open http://localhost/phpinfo.php in your web browser and you will get something like this:

You should see all of the info about your PHP installation listed on the page.

Install MySQL

Again, type the following command in your Terminal

> sudo apt-get install mysql-server

Note: As MySQL is installing, it will ask you to configure your root password. Make sure that you type it correctly, as it will only ask you once.

You might need to manually start MySQL for the first time, do so by typing this command in your Terminal.

> sudo /etc/init.d/mysql start

Testing MySQL

After that is finished, you can test MySQL by running this, where 123 is your password

> mysql -uroot -p123
mysql> show databases;
mysql> quit

Install PHPMyAdmin

As usual, run the following command in terminal

> sudo apt-get install phpmyadmin

This process is quite, as slow as MySQL installation and there are time you need to provide some information in order to complete the process but it quite optional. Once finish you need to create a soft link in /var/www/ to /usr/share/phpmyadmin using these command.

> sudo ln -s /usr/share/phpmyadmin /var/www/phpmyadmin

Now open up http://localhost/phpmyadmin your web browser.

16 PHP Frameworks To Consider For Your Next Project

FeedMalaya is a social blog aggregator that pull out the best content from Malaysian bloggers was launched on June 7th, 2009 developed by Bat InfoMalaya and myself.

Technology Behind FeedMalaya?

The development period only took us 9 days from first draft to launch using CodeIgniter (with enhancement using Codenitive), SimplePie, jQuery, Savvy.UI, FlexiGrid for jQuery and Facebook Connect for CodeIgniter.

Why Another Blog Aggregator?

Firstly, I can’t find anything good aggregator I can follow mainly for local content. Well nothing against the other Blog Aggregator or Social Bookmarking currently available or being developed at the moment but this is my personal point of view and I personally think there are others who feel the same way as me.

How do FeedMalaya Grab Fresh Content?

Currently we fetch a blog or website every minute using RSS/ATOM feed using SimplePie and PHP CLI. This method is suitable since we haven’t reach a bottleneck due to the numbers of site in queeue. However we do understand that one day we have to consider more advanced algorithm when the it became a requirement.

OpenID was the first option for FeedMalaya, why did you change it to Facebook Connect?

We did try OpenID for CodeIgniter find the documentation and implementation not as friendly as we consider it to be so we look for alternative. Here some of the key factor why Facebook Connect become our choice:-

• High number of Malaysian user who already have a Facebook account.
• Single vendor, single documentation and single achitecture.
• Low amount of time and effort to implement the integration.

Any last word?

Visit and join us at FeedMalaya or FeedMalaya Mobile. The development still continue while we serve you fresh content.
