			0 ignored issues – show Bug introduced 2016-07-26 12:49 UTC by Report Bug Copy Issue Report The variable `$_FILTER` seems to never exist, and therefore `isset` should always return `false`. Did you maybe rename this variable? This check looks for calls to `isset(...)` or `empty()` on variables that are yet undefined. These calls will always produce the same result and can be removed. This is most likely caused by the renaming of a variable or the removal of a function/method parameter. Loading history...

			0 ignored issues – show Compatibility Best Practice introduced 2016-07-26 12:49 UTC by Report Bug Copy Issue Report Use of `global` functionality is not recommended; it makes your code harder to test, and less reusable. 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...
