Mudit, Using the Symfony HTTP Foundation package makes it so you dont have to use the GLOBAL variables ($_GET, $_POST, etc).

You should never trust data that can be submitted by an end user so you should filter it. Symfony gives you some help with that,but you can also go the extra mile and run their function $request->request->filter('email', 'default value', false, INPUT_VALIDATE_EMAIL); which will validate an input with the name of email and make sure it is a valid email address.
