Zend Framework: How to intentionally throw a 404 e

Question

I would like to intentionally cause a 404 error within one of the controllers in my Zend Framework application. How can I do this?

Answer 1

You can always set the response code manually, without throwing any exceptions.

$this->_response->clearBody();
$this->_response->clearHeaders();
$this->_response->setHttpResponseCode(404);

Answer 2

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);
