Examples

Example #1 Yaf_Dispatcher::catchException() example


/* if you defined a ErrorController like following */
<?php
class ErrorController extends Yaf_Controller_Abstract {
     /** 
      * you can also call to Yaf_Request_Abstract::getException to get the 
      * un-caught exception.
      */
     public function errorAction($exception) {
        /* error occurs */
        switch ($exception->getCode()) {
            case YAF_ERR_NOTFOUND_MODULE:
            case YAF_ERR_NOTFOUND_CONTROLLER:
            case YAF_ERR_NOTFOUND_ACTION:
            case YAF_ERR_NOTFOUND_VIEW:
                echo 404, ":", $exception->getMessage();
                break;
            default :
                $message = $exception->getMessage();
                echo 0, ":", $exception->getMessage();
                break;
        }
     } 
}
?>

The above example will output something similar to:

/* now if some error occur, assuming access a non-exists controller(or you can throw a exception yourself): */
404:Could not find controller script **/application/controllers/No-exists-controller.php
