I would like to intentionally cause a 404 error within one of the controllers in my Zend Framework application. How can I do this?
You can always set the response code manually, without throwing any exceptions.
$this->_response->clearBody();
$this->_response->clearHeaders();
$this->_response->setHttpResponseCode(404);
A redirect to a 404 would be:
throw new Zend_Controller_Action_Exception('Your message here', 404);
Or without Exception:
$this->_response->clearBody();
$this->_response->clearHeaders();
$this->_response->setHttpResponseCode(404);
