			0 ignored issues – show Duplication introduced 2017-05-05 10:41 UTC by Report Bug Copy Issue Report This class seems to be duplicated in your project. 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...

			0 ignored issues – show Bug introduced 2017-01-12 12:49 UTC by Report Bug Copy Issue Report There is no parameter named `$iterable`. Was it maybe removed? This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function. Consider the following example. The parameter `$italy` is not defined by the method `finale(...)`. /** * @param array $germany * @param array $island * @param array $italy */ function finale($germany, $island) { return "2:1"; } The most likely cause is that the parameter was removed, but the annotation was not.
