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...

		0 ignored issues – show Bug introduced 2019-10-24 21:58 UTC by Report Bug Copy Issue Report It seems like `setSourceQueryParam()` 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...

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...
