Murmur users online grapher PHP using ICE
ver 0.4 2011.06.10, 15:44 
author _KaszpiR_ kaszpir at gmail dot com
code is under GPL

Requirements:
- PHP installed in CLI (so you can run it in command line)
  Make sure the first line of this file points to the pworking php cli inrepreter
- ICE framework on server
- Murmur server with ICE enabled

/////////////////////////////////////////////////////////////////////////////////////////////////////

Configuration:
1. link creation
create a symlink to thie file in the following format:
    murmurice_ip_port_sid_description
where ip/port correspond to the ip and port on which the mumble ice interface listens to
sid is the server id we want to query (mumble can run multiple servers )
description - any kind of short text where _ will be replaced with spaces

By default script tries to connect 127.0.0.1:6502 and query server id 1

2. ice profile configuration
 This is not needed with ice 3.4.1
 Scroll down in this file and change 
 $ice_profile = 'Murmur'; 
 to the profile that is installed on the server, this is required if you have multiple Ice profiles for various applicaitions.


/////////////////////////////////////////////////////////////////////////////////////////////////////

Script returns:
channels number = number of existing channels on server (with temoprary ones)
players number = number of all connected users on server
registered number = number of connected and registered users on server
unregistered number = number of connected and not registered users on server
chanlinks number = linked chanels
error number = this is set to 1 when there is error with communicatind with server via ice

On any error script exits with status 1, otherwise it is 0.
