The ZF2 MVC layer incorporates and utilizes a custom
Zend\Mvc\MvcEvent. This event is created during
Zend\Mvc\Application::run(), and is passed
directly to all events that method triggers. Additionally, if you
mark your controllers with the
Zend\Mvc\InjectApplicationEvent interface, it
will be injected into those controllers.
MvcEvent adds accessors and mutators for the
"Result", usually the result of dispatching a controller
The methods it defines are:
Within Application::run(), the event is injected
with the Request, Response, and Router immediately. Following the
route event, it will be injected also with the
RouteMatch object encapsulating the results of
Since this object is passed around throughout the MVC, it is a common location for retrieving the results of routing, the router, and the request and response objects. Additionally, we encourage setting the results of execution in the event, to allow event listeners to introspect them and utilize them within their execution. As an example, the results could be passed into a view renderer.
