Disallow usage of superglobals #91
Description
Report any occurence of super global (http://php.net/manual/en/language.variables.superglobals.php). In ideal world there should not be any, because the abstraction layer from one of Composer libraries (e.g. symfony/http-foundation) should be used.
Superglobals:
- $GLOBALS (maybe not this one)
- $_SERVER
- $_GET
- $_POST
- $_FILES
- $_COOKIE
- $_SESSION (maybe not this one)
- $_REQUEST
- $_ENV
