How to check if a controller exists using Zend Framework

Question

I'm writing a plugin for my Zend Framework app and want to do a quick check to see if a controller exists. Can anyone point me in the right direction?

Answer 1

Use the isDispatchable - Method of the front controller by passing it a Zend_Controller_Request_Abstract instance.

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