		0 ignored issues – show Security Bug introduced 2017-01-21 20:11 UTC by Report Bug Copy Issue Report It seems like `$aParsed` defined by `parse_url($sUrl)` on line `117` can also be of type `false`; however, `vsc\infrastructure\urls\...arserA::loadParsedUrl()` does only seem to accept `array`, 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...
