The SendResponse Event

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()

Listeners

Currently, three listeners are listening to this event at different priorities based on which listener is used most.

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.

Triggered By

This event is executed when the MvcEvent::FINISH event is triggered, with a priority of -10000.
