		0 ignored issues – show Bug introduced 2017-07-23 23:31 UTC by Report Bug Copy Issue Report It seems like `resolveTransformer()` 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...

It is generally a best practice as it is often more readable to use concatenation instead of interpolation for variables inside strings. // Instead of $x = "foo $bar $baz"; // Better use either $x = "foo " . $bar .
