vote uses the super-global variable $_SERVER which is generally not recommended.
Instead of super-globals, we recommend to explicitly inject the dependencies
of your class. This makes your code less dependent on global state and it
becomes generally more testable:
// BadclassRouter{publicfunctiongenerate($path){return$_SERVER['HOST'].$path;}}// BetterclassRouter{private$host;publicfunction__construct($host){$this->host=$host;}publicfunctiongenerate($path){return$this->host.$path;}}classController{publicfunctionmyAction(Request$request){// Instead of$page=isset($_GET['page'])?intval($_GET['page']):1;// Better (assuming you use the Symfony2 request)$page=$request->query->get('page',1);}}
