It seems like you are loosely comparing ip2long($_SERVER[$k]) of type integer to the boolean false. If you are specifically checking for non-zero, consider using something more explicit like > 0 or !== 0 instead.

            {
                $ip = $_SERVER[$k];
            }
        }

        return $ip;
