		0 ignored issues – show Security Bug introduced 2016-02-23 18:13 UTC by Report Bug Copy Issue Report It seems like `$user` defined by `\User::newFromName($page->getUserText(), false)` on line `81` can also be of type `false`; however, `CreditsAction::userLink()` does only seem to accept `object<User>`, did you maybe forget to handle an error condition? This check looks for type mismatches where the missing type is `false`. This is usually indicative of an error condtion. Consider the follow example <?php function getDate($date) { if ($date !== null) { return new DateTime($date); } return false; } This function either returns a new `DateTime` object or false, if there was an error. This is a typical pattern in PHP programming to show that an error has occurred without raising an exception. The calling code should check for this returned `false` before passing on the value to another function or method that may not be able to handle a `false`. Loading history...
