			0 ignored issues – show Bug introduced 2017-11-26 13:45 UTC by Report Bug Copy Issue Report Since `$abilities` is declared private, accessing it with `static` will lead to errors in possible sub-classes; consider using `self`, or increasing the visibility of `$abilities` to at least protected. Let’s assume you have a class which uses late-static binding: class YourClass { private static $someVariable; public static function getSomeVariable() { return static::$someVariable; } } The code above will run fine in your PHP runtime. However, if you now create a sub-class and call the `getSomeVariable()` on that sub-class, you will receive a runtime error: class YourSubClass extends YourClass { } YourSubClass::getSomeVariable(); // Will cause an access error. In the case above, it makes sense to update `SomeClass` to use `self` instead: class SomeClass { private static $someVariable; public static function getSomeVariable() { return self::$someVariable; // self works fine with private. } } Loading history...

			0 ignored issues – show Bug introduced 2017-07-14 09:10 UTC by Report Bug Copy Issue Report It seems like `getRepository()` must be provided by classes using this trait. How about adding it as abstract method to this trait? This check looks for methods that are used by a trait but not required by it. To illustrate, let’s look at the following code example trait Idable { public function equalIds(Idable $other) { return $this->getId() === $other->getId(); } } The trait `Idable` provides a method `equalsId` that in turn relies on the method `getId()`. If this method does not exist on a class mixing in this trait, the method will fail. Adding the `getId()` as an abstract method to the trait will make sure it is available. Loading history...

			0 ignored issues – show Bug introduced 2017-11-26 13:45 UTC by Report Bug Copy Issue Report The property `app` does not exist. Did you maybe forget to declare it? In PHP it is possible to write to properties without declaring them. For example, the following is perfectly valid PHP code: class MyClass { } $x = new MyClass(); $x->foo = true; Generally, it is a good practice to explictly declare properties to avoid accidental typos and provide IDE auto-completion: class MyClass { public $foo; } $x = new MyClass(); $x->foo = true; Loading history...
