How to check if controller exists using Zend Framework

Question

I am writing a plugin for my Zend Framework application and I want to quickly check if the controller exists. Can someone point me in the right direction?

Answer 1

Use the isDispatchable method, the front controller method, passing it an instance of Zend_Controller_Request_Abstract.

if( $front->getDispatcher()->isDispatchable($testRequest) )  
{  
    //things to do
}
