Now a days, my default choice of framework is always Zend Framework. However, I have to maintain a couple live projects in CodeIgniter from early days. I feel its very important to have tests around critical applications, so I have attempted a couple times to integrate PHPUnit with CodeIgniter but failed every time – well, until now.
I’ve managed it this time with hooks. It provides a clean way of bootstrapping the framework and then performing tests on the Model layer – for me testing the model layer has been sufficient. The use is very simple as it does not require any change in how a regular CodeIgniter application is built.
Grab the code from github.
Example – /tests/PostTest.php
<?php
class PostTest
extends PHPUnit_Framework_TestCase
{
private $CI;
public function setUp
()
{
$this->CI = &get_instance
();
$this->CI->load->database('testing');
}
public function testGetsAllPosts
()
{
$this->CI->load->model('post');
$posts = $this->CI->post->getAll();
$this->assertEquals(1, count($posts));
}

It took me an hour to properly install the latest versions of ruby, rails and its mysql binder. Although its less than a 5 mins task, I had to search in forums, blogs to deal with the various errors. So just posting this so its easy for someone else to get done with this in 5 mins.
1. Open Terminal and install RVM (Ruby Version Manager)
bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)
2. Enter the following in ~/.bash_profile and/or ~/.bashrc (replace YOUR USER NAME with the username you’re logged in with):
[[ -s "/home/YOUR USER NAME/.rvm/scripts/rvm" ]] && source "/home/YOUR USER NAME/.rvm/scripts/rvm" # This loads RVM into a shell session.
3. Install Ruby 1.9.2

This post is more than 1 year old. It solved the issues when the SDK was first released and facebook had lack of documentation. However, now facebook has very rich set of
documnetation and you should follow that instead!
The new Facebook API has already spread over the application developers and if you’re like me, you’ve already got your hands dirty to see how this new thing works. If you have tried to follow the documentation to authorize/get session in your canvas application, it is likely you have already hit roadblocks. Well, I am no savior but I have glued together a few clues and got it working for myself.
I am assuming that you have already created your application by following the Getting Started section from the official documentation. Also, this is for IFrame based applications only.
Enough talking, let’s get some code.
Step 1: Get the new SDK
Download the new SDK from github. We will only need the facebook.php file from the src folder. In our project directory, let’s create a folder called “lib” and put the file there.
Step 2: A configuration file
Let’s now create a configuration file to store our facebook configuration. Let’s name it config.php. Here goes the source:
<?php
define("FACEBOOK_APP_ID", '113795715321151');
define("FACEBOOK_API_KEY", '064baf5fb98de050cd7b9a001ca1988b');
define("FACEBOOK_SECRET_KEY", '430f43c01f6dfe02c284b4545976f9ce');
define("FACEBOOK_CANVAS_URL", 'http://apps.facebook.com/emran-test-app/'); Step 3: Application Main Page
This file will be the main entry point to our facebook application. It just instantiates the facebook object, sets the configuration and checks for a valid session. If it does not find a valid session, it redirects to the login page. For first time visitors, it will be the authorization page. On later requests, the operation will occur in the background – without any user interaction.
<?php
include_once 'lib/facebook.php';
include_once 'config.php';
$facebook = new Facebook
(array(
'appId' => FACEBOOK_APP_ID
,
'secret' => FACEBOOK_SECRET_KEY
,
'cookie' => true,
'domain' => 'phpfour.com'
));
$session = $facebook->getSession();
if (!$session) {
$url = $facebook->getLoginUrl(array(
'canvas' => 1,
'fbconnect' => 0
));
echo "<script type='text/javascript'>top.location.href = '$url';</script>";
} else {
try
{
$uid = $facebook->getUser();
$me = $facebook->api('/me');
$updated = date("l, F j, Y", strtotime($me['updated_time']));
echo "Hello " . $me['name'] . "<br />";
echo "You last updated your profile on " . $updated;
} catch
(FacebookApiException
$e) {
echo "Error:" . print_r($e, true);
}

I presented this talk on the Soft Expo 2010 – the largest software fair in Bangladesh. The intention was to clear some of the misconception about PHP, the growth of PHP, how it can fit in the enterprise now, etc.
After these, I shed light on some topics that a company/developer should keep in mind in order to write good software in PHP. This was followed by live session on caching, mysql query optimization, use of Xdebug, etc.
So here goes the presentation:
And a big thanks to Ivo Jansch’s “PHP in the real wolrd” presentation, from where I took inspiration.
Cheers!

CodeIgniter is one of my favorite framework and I often use it for developing application quickly. Although it is very flexible in most cases, I find its naming convention to be strict. Many times I have faced this problem when my controller’s class name and a model/library’s class names are the same – a Fatal error is inevitable and I have to forcefully change the name of the conflicting class to something less desirable (say from Users to UsersModel). Today I wanted to end this problem.
So I extended the CI_Router core class and made change to the _validate_request method. Now I can name my controller classes in this fashion: UsersController and it resides on the file system as controllers/UsersController.php. If you’ve tried other established frameworks, you should notice that this naming convention is widely used. So, if you have the same need, then just download the MY_Router.php file and put it on your application/libraries folder. That’s it.
Here is how your controller would start:
<?php
class UsersController extends Controller
{
public function __construct()
{
parent::__construct();
}
}
