Version 1.0 of this PHP class was produced by Goldeye on 12/26/07. It provides functions to report on the number of players logged on -- as well as the number playing -- in an ASSS zone or specific arenas. It is currently only compatible with ASSS's new Ping_Protocol. It's intended function is to put this information on a zone's website.
The code at the top is demonstration using SSCE and it's two most active arenas. It can be removed without affecting the class. Basic PHP knowledge is required to adapt the script
Feel free to contact the author with any requests or bugs with the script.
