Weee, thats a long title. Should be even longer, thing is to display it on this website side panel.
As some of you are aware, we can access these numbers by reading contents of this link:
http://www.daimonin.org:13326/But... doing that in interactive way is a different matter. If one wants to read it from inside of php script, there are several ways.
1. fopen function
1. curl, if present
2. fsocket stuff
1) easiest to use, though its forbidden on most servers. so let's skip it.
2) curl, if present (and it should be on most servers) gives more options in this matter. but it also requiring much more coding/scripting in php
3) honestly, i didnt dig in to it yet
so, while this curl thing seems complicated, its possible, and in the effect we could have number of players online read from above URL address to be a part of this website's side panels. AFAIK, we had that a while ago, on previous site. It'd be great to have it back.
This post really happened only because i've found a nice script simplifying curl access to URL contents. And its tested, as far as I could on my local apache

The only concern I have about it is that in the case of game server not running (I assume its the origin of port 13326 being open), website would load very long, with eventual errors.
I'm not sure if I could pull up this script to be aware of game server being active or not, so emedding its code to this site would be just a rush, but if someone else is interested in reviving this functionality, im hope it's possible for it to be working again.
There's the script:
http://codepad.org/ZkfT7sIn (technically, it will read both curl and fsocket, whichever is available) and I also wrote small dissasembling script to read player numbers from 13326 port contents.
