This check looks for the bodies of `if` statements that have no statements or where all statements have been commented out. This may be the result of changes for debugging or the code may simply be obsolete. These `if` bodies can be removed. If you have an empty if but statements in the `else` branch, consider inverting the condition. if (rand(1, 6) > 3) { //print "Check failed"; } else { print "Check succeeded"; } could be turned into if (rand(1, 6) <= 3) { print "Check succeeded"; } This is much more concise to read.

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: // Bad class Router { public function generate($path) { return $_SERVER['HOST'].$path; } } // Better class Router { private $host; public function __construct($host) { $this->host = $host; } public function generate($path) { return $this->host.$path; } } class Controller { public function myAction(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); } } Loading history...
