I'm following a Symfony tutorial and am currently on The Event Dispatcher section. In the first code block (after the composer part) I'm instructed to set up the dispatcher
// dispatch a response event
$this->dispatcher->dispatch(new ResponseEvent($response, $request), 'response');
I'm using PHPStorm, and when I create the ResponseEvent class it is asking for 4 arguments
new ResponseEvent($kernel, $request, $requestType, $response)
While I could create a $kernel element by importing the HttpKernelInterface, I'm unsure if this is correct.
I also have no idea where to get the $requestType from, since the ResponseEvent class definition says that this should be of type int and I only know of request types in string format (e.g. 'GET', 'POST' etc).
Here is the full file in case I have made a mistake elsewhere.
The tutorial that you are following wants you to use the Simplex ResponseEvent, that method signature is for the kernel ResponseEvent
At the top of your file you should see something like this:
use Symfony\Component\HttpKernel\Event\ResponseEvent;
Replace it with
use Simplex\ResponseEvent;
