Here is very simple way how to use Zend Framework and Yui Php Loader Utility.
Below is code. This helper returns YAHOO_util_Loader object so check docs at http://developer.yahoo.com/yui/phploader/
require_once 'phploader/phploader/loader.php'; require_once 'Zend/View/Helper/Abstract.php'; class Loota_View_Helper_PhpYuiLoader extends Zend_View_Helper_Abstract{ static private $loader; public function __construct(){ if(Loota_View_Helper_phpYuiLoader::$loader === null){ Loota_View_Helper_phpYuiLoader::$loader = new YAHOO_util_Loader("2.8.0"); } } public function phpYuiLoader(){ return Loota_View_Helper_phpYuiLoader::$loader; } }
