This check looks for PHPDoc comments describing methods or function parameters that do not exist on the corresponding method or function.

The parameter `$ireland` is not defined by the method `finale(...)`. /** * @param array $germany * @param array $ireland */ function finale($germany, $island) { return "2:1"; } The most likely cause is that the parameter was changed, but the annotation was not.
