Integrating Zend with CodeIgniter

Last day, I had to integrate Zend Framework with Codeigniter. This came out to be quite easier then i thought. So here are the steps for integrating zend
framework with codeigniter.

Step 1: Copy the Zend folder from inside the library folder of Zend Framework

Setp 2: Create a folder inside your system, such as ../system/zf.

Step 3: Create a helper file like: zf_helper.php and place it into ../system/application/helpers/
Here is the code for zf_helper.php file

    //For Linux OS
    ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . BASEPATH . '/zf/');
    require_once 'Zend/Loader.php';
    
    //For windows OS
    ini_set('include_path', ini_get('include_path') . PATH_SEPARATOR . str_replace('/', '\\', BASEPATH) . 'zf\\');
    require_once ('Zend/Loader.php');
?>

Step 4: Add this helper to your ../system/application/config/autoload.php file

    $autoload['helper'] = array('url', 'form', 'date', 'zf');   //zf is the helper that we have added for zend framework integration
?>

Step 5: Now you can use any modules of Zend Framework from CodeIgniter, like in a controller file

    class SomeTest extends Controller {
        //in some function
        //.....
        //....
        //....
        function someFunction() {
          //load Zend Classes
            Zend_Loader::loadClass('Zend_Gdata');
            Zend_Loader::loadClass('Zend_Gdata_Calendar');
            Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
            Zend_Loader::loadClass('Zend_Http_Client');
            $username = "someuser@gmail.com";
            $password = "somepassword";
            $gCalen = Zend_Gdata_Calendar::AUTH_SERVICE_NAME;
            $client = Zend_Gdata_ClientLogin::getHttpClient($username, $password, $gCalen);
            $gCalen = new Zend_Gdata_Calendar($client);
            //and so on
        }
    }
?>
