		0 ignored issues – show Bug introduced 2016-08-11 13:05 UTC by Report Bug Copy Issue Report It seems like `getElement()` 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 2016-08-11 13:05 UTC by Report Bug Copy Issue Report The method `getElement()` does not exist on `DOMElement`. Did you maybe mean `getElementsByTagName()`? 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.

		0 ignored issues – show Documentation introduced 2016-08-11 13:05 UTC by Report Bug Copy Issue Report `$child->getElement()` is of type `object<DOMElement>`, but the function expects a `object<nstdio\svg\XMLDocumentInterface>`. It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { } $x = '123'; // string "123" // Instead of acceptsInteger($x); // we recommend to use acceptsInteger((integer) $x); Loading history...
