laminas/laminas-mvc
Laminas MVC is a modular, event-driven MVC framework for PHP applications. It provides routing, controllers, view integration, dependency injection, and configuration management, helping you build scalable, maintainable web apps and APIs on top of Laminas components.
laminas-mvc defines and utilizes a custom Laminas\EventManager\Event for updating
the response object prior to emitting it, Laminas\Mvc\ResponseSender\SendResponseEvent.
The event allows listeners to set response headers and content.
The methods it defines are:
setResponse($response)getResponse()setContentSent()contentSent()setHeadersSent()headersSent()Currently, three listeners are listening to this event at different priorities based on which listener is used most.
| Class | Priority | Method Called | Description |
|---|---|---|---|
Laminas\Mvc\SendResponseListener\PhpEnvironmentResponseSender |
-1000 | __invoke |
This is used in HTTP contexts (this is the most often used). |
Laminas\Mvc\SendResponseListener\ConsoleResponseSender |
-2000 | __invoke |
This is used in console contexts. |
Laminas\Mvc\SendResponseListener\SimpleStreamResponseSender |
-3000 | __invoke |
This is used in HTTP context to pass through stream directly to output. |
Because each listener has negative priority, adding your own logic to modify the
Response involves adding a new listener without priority (as priority defaults
to 1); thus, your own listener will execute before any of the defaults.
This event is executed when the MvcEvent::FINISH event is triggered, with a priority of -10000.
