Security Bug introduced by
It seems like $parts defined by parse_url($url) on line 30 can also be of type false; however, Generics\Util\Arrays::hasElement() 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.
