Master Server query list?

Hi.

I was wondering if anyone has made a (possibly PHP) script that they would be willing to share, that I can use to query a master server I have setup and show the list of servers connected to it (and possibly clients if that's possible).

I would like to be able to run it from a web browser, if possible. And can make it query my own master server.

If anyone knows of such a thing, it would be greatly appreciated.
