symfony2 – Access to Request in a Controller

<?php

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;

class TestController extends Controller
{
   //Inject Request HTTP Component in your function then able to exploit it
   public function myFunctionAction(Request $request)
   {
      //BASICS

      //retrieve $_POST variables from request
      $postRequest = $request->request->get('my_data');
      //retrieve $_GET variables from request
      $getRequest = $request->query->get('my_data');
      //get current locale
      $locale = $request->getLocale();
   }
}

Note that injected Request object applies to current request (it may or may not equal to master request).
