Although I've never used this function, based on the documentation it seems that the above code should also include the following: if ( ! is_array( $url ) ) // Added - Randy // Parse the original URL $parse_url = parse_url($url); // allow parts to be a url Added - Randy if ( ! is_array( $parts ) ) $parts = parse_url( $parts );

This function has a useful undocumented feature - the defaults are set in such a way that calling it with no parameters returns the full URL of the page being accessed.

If you are looking for a PHP Version of this function, follow the link below: http://www.mediafire.com/?zjry3tynkg5 Note: I would have added the function here, but I just couldn't get it past the line restrictions without making it impossible to read. Enjoy.
