Getting $_GET parameters from route in Zend Framework 2

Question

Zend Framework 1 had a very simple way of parsing URL routes and setting found params in the $_GET superglobal for easy access. Sure, you could use ->getParam($something) inside the controller, but if the param was found in the URL, it was also accessible via $_GET.

Example for url mypage.com/mymodule/mycontroller/myaction/someparam/5:

ZF1

$this->getParam('someparam'); // 5
$_GET['someparam']; // 5

ZF2

$this->getEvent()->getRouteMatch()->getParam('someparam'); // 5
$_GET['someparam'] // undefined index someparam

Obviously, the difference is that ZF2 does NOT put the route params into the $_GET superglobal.

How do I make it put the parsed parameters into the $_GET superglobal, since extending the controller and just defining a constructor that does that is out of the question (because RouteMatch is not an object yet and cannot be called from the controller's constructor)?

Calling $_GET = $this->getEvent()->getRouteMatch()->getParam('someparam'); in every one of my controllers would work, but I don't want that.

In other words, following the example URL from above, I want to be able to do $_GET['someparam'] and still get the value "5" in any component in the application.

Edit: Looks like I wasn't clear enough, so I'll try to clarify some more. I want whatever param I enter in the URL via /key/value formation to be available in $_GET instantly. I don't really have a problem with getting the param, I know how to get it and I extended Zend's controller so I can just call $this->getParams again like in ZF1, and now all controllers extend that one, I just want the params from the URL to automatically be in $_GET as well, so I can access them easily in third party components which use $_GET natively.

Edit 2: Updated as reaction to Samuel Herzog's answer: I don't really mind invalidating the SRP in this case, because the libraries are built in such a way that they need direct access to $_GET - they do their own filtering and directly depend on this superglobal. They also directly fetch $_FILES and $_POST for processing, it's just the way their code works.

I've made the following method in the abstract controller: $this->mergeGet(); which basically makes $_GET absorb all the route matched params and everything works as intended, but seeing as the libraries will be required in every controller/action, it might get tedious to call that method every time. If only the controller had an init() method like in ZF1...

Answer 1

In ZF2, Im using this

$getparams = $this->getRequest()->getQuery();
