		0 ignored issues – show Coding Style introduced 2018-02-25 17:05 UTC by Report Bug Copy Issue Report `checkPermissions` uses the super-global variable `$_SESSION` which is generally not recommended. Instead of super-globals, we recommend to explicitly inject the dependencies of your class. This makes your code less dependent on global state and it becomes generally more testable: // Bad class Router { public function generate($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...

Instead of relying on `global` state, we recommend one of these alternatives: 1. Pass all data via parameters function myFunction($a, $b) { // Do something } 2. Create a class that maintains your state class MyClass { private $a; private $b; public function __construct($a, $b) { $this->a = $a; $this->b = $b; } public function myFunction() { // Do something } } Loading history...
