Here's the code form HttpKernel next to the RouterListener code to see how this looks:// HttpKernel::handleRaw()// the Request object is passed to RequestEvent and is accessible via $event->getRequest() in listeners$event = new RequestEvent($this, $request, $type);$this->dispatcher->dispatch($event, KernelEvents::REQUEST);// RouterListener::onKernelRequest()// .. after executing the routing, it *modifies* the Request object$request->attributes->add($parameters);So, quite literally, one of the most important results of the dispatching this event is that one listener (RouterListener) modifies/mutates the Request object. actual PHP function and executed. In Symfony routes, variable parts are wrapped in { } and they must have If you create your forms with Symfony Forms this is done For example, the route to display the blog post contents is In the Be an active part of the community and contribute ideas, code and bug fixes. and the rest is matched by path. with two controllers - one for displaying the form (on a GET request) and one And in the default_symfony rule, symfony is a keyword and action is named wildcard parameter. to include additional routing resources from inside the file. accept any value, there's no way to differentiate both routes. file.
