		0 ignored issues – show Coding Style introduced 2015-11-21 13:17 UTC by Report Bug Copy Issue Report `action` uses the super-global variable `$GLOBALS` which is generally not recommended. Instead of super-globals, we recommend to explicitly inject the dependencies of your class. This makes your code less dependent on global state and it becomes generally more testable: // Bad class Router { public function generate($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...

Did you maybe mean `applyFilters()`? This check marks calls to methods that do not seem to exist on an object. This is most likely the result of a method being renamed without all references to it being renamed likewise. Loading history...

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

How about adding an `instanceof` check? If you access a property on an interface, you most likely code against a concrete implementation of the interface.

		0 ignored issues – show Coding Style Compatibility introduced 2015-11-21 13:17 UTC by Report Bug Copy Issue Report The method `redirect()` contains an exit expression. An exit expression should only be used in rare cases. For example, if you write a short command line script. In most cases however, using an `exit` expression makes the code untestable and often causes incompatibilities with other libraries. Thus, unless you are absolutely sure it is required here, we recommend to refactor your code to avoid its usage. Loading history...
