1. How to Access PUT data in Zend Framework

The first thing to know is the difference between twig global, filter and functions (or just how the look in twig templates).

Global

{{ global_variable }}

Filter

{{ 'some sort of text'|filter }}

Function

{% function('some variable or text') %}

If you want more information look here:
http://twig.sensiolabs.org/doc/templates.html

For the following steps remember to change the ‘Bundle’ and ‘NameBundle’ to your bundles values. Also note that the following code is just for creating filters.

Step 1: Create the filter

Create a file Bundle/NameBundle/Extension/MyTwigExtension.php and use the following code inside it.

<?php
namespace Bundle\NameBundle\Extension;
use Symfony\Component\HttpKernel\KernelInterface;
class MyTwigExtension extends \Twig_Extension
{
    public function getFilters()
    {
        return array(
            'uppercase_first_letter' => new \Twig_Filter_Method($this, 'uppercase_first_letter'),
            'var_dump' => new \Twig_Filter_Function('var_dump')
        );
    }

    function uppercase_first_letter($var){
        return ucwords($var);
    }

    public function getName()
    {
        return 'recensus_twig_extension';
    }
}

So I’ve created two filters that I can use in my twig templates, uppercase_first_letter and var_dump. var_dump is already a function within php so that just works without having to create the method within the MyTwigExtension class. uppercase_first_letter require me to create a public method within the class.

Notice the different classes used, Twig_Filter_Method for a custom methods and Twig_Filter_Function for a php method.

Step 2: Register with config

Then you need to add the following code to the bottom of the config file (/app/config/config.yml).

services:
    anywordyouwant.twig.extension.mytwigextension:
        class: Bundle\NameBundle\Extension\MyTwigExtension
        tags:
            -  { name: twig.extension }

Step 3: Use the filters

Inside your twig templates

{{ 'what ever you want'|uppercase_first_letter }}

1. Domain Registration
Registered the domain name with 123-reg.co.uk. I choose them because they are reasonably priced and you get control over the DNS records which they don’t charge you extra for and they haven’t gone down in. (Cost: £12)

2. Setup Cloudflare
Cloudflare.com is an amazing service that give you a DNS server which blocks spam, protects against security attacks, caches content using a CDN and a lot of other features. Well worth the free price tag, takes about 10 minutes to setup, I only wish they gave you the nameservers at the beginning of the setup and they had Google App’s DNS settings as a one click button. (Cost: free)

3. Setup Google Apps
Just in case you don’t know Google App’s give you Gmail, Google Calendar, Google Sites and Google Docs all under your own domain (free for up to 10 users). Again well worth the free price tag (although you have to look hire for the free version), just don’t forget to setup the subdomains. (Cost: free)

4. Setup Webspace and Upload Holding Page
I’ve got my own server (well Welford Media Ltd has) and I’ve just created a new domain and uploaded my holding page. If you haven’t got hosting you could go to Hostpapa.co.uk and click install wordpress, then download a coming soon template (see http://www.net-kit.com/12-free-attractive-themes-templates-for-coming-soon-pages/ or http://www.hongkiat.com/blog/coming-soon-templates-tutorials/). (Cost: £2 per month)

5. Signup to MailChimp
Mailchimp enables you to send out tracked email newsletters to subscribers and they have a free account which give you 2000 subscribers! After signing up put the signup form on your website. (Cost: free)

That’s the easy bit done, now i’ve just got build the app, do the sales and marketing, convert leads and make money. Also if possible get funding, find mentors and hire staff.

The video below shows you step by step however it’s 5 minutes long and I can explain in 5 lines.

1. Download the Adobe Air SDK, unzip.
2. Open Netbenas, Create a new PHP Project
3. On the 3rd page of creating a new project (Run Configuration) choose Run As: Script (run in command line)
4. Then choose AdobeAIRSDK\bin\adle.exe as the PHP Interpreter
5. The final step which isn’t in the video, (after creating the index.html file and application.xml file) click the Run Project button and it will ask you for Run Configuration, makes sure you choose application.xml as the Index File NOT index.html.

Hopefully this will work for you as well!

Fatal error: Uncaught exception 'Zend_Session_Exception' with message 'session has already been started by session.auto-start or session_start()

The reason for the error is that the session already existed from my first visit and CGI was the owner, when I changed it to Apache module apache did not have permission to change the session data. The solution, shut down your browser (or start a privacy mode) and then try and view your website. Everything should work fine afterwards.
