			0 ignored issues – show Comprehensibility Bug introduced 2021-03-10 14:02 UTC by Report Bug Copy Issue Report It seems like you call parent on a different method (`wrapClass()` instead of `wrap()`). Are you sure this is correct? If so, you might want to change this to `$this->wrapClass()`. This check looks for a call to a parent method whose name is different than the method from which it is called. Consider the following code: class Daddy { protected function getFirstName() { return "Eidur"; } protected function getSurName() { return "Gudjohnsen"; } } class Son { public function getFirstName() { return parent::getSurname(); } } The `getFirstName()` method in the `Son` calls the wrong method in the parent class.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository. Loading history...
