abstract class Zend_Controller_Action { .... public function __call($methodName, $args) { if ('Action' == substr($methodName, -6)) { require_once 'Zend/Controller/Action/Exception.php'; $action = substr($methodName, 0, strlen($methodName) - 6); require_once 'Zend/Controller/Action/Exception.php'; throw new Zend_Controller_Action_Exception(sprintf('Action "%s" does not exist and was not trapped in __call()', $action), 404); }

    require_once 'Zend/Controller/Action/Exception.php';
    throw new Zend_Controller_Action_Exception(sprintf('Method "%s" does not exist and was not trapped in __call()', $methodName), 500);
}

}

there are too many require_once() in __call($methodName, $args) method, can be rewriten like this:

abstract class Zend_Controller_Action { .... public function __call($methodName, $args) { require_once 'Zend/Controller/Action/Exception.php'; if ('Action' == substr($methodName, -6)) { $action = substr($methodName, 0, strlen($methodName) - 6); throw new Zend_Controller_Action_Exception(sprintf('Action "%s" does not exist and was not trapped in __call()', $action), 404); } throw new Zend_Controller_Action_Exception(sprintf('Method "%s" does not exist and was not trapped in __call()', $methodName), 500); } }
