Due to the recently released Teamspeak 3 BETA I have made a connection class in PHP to communicate with the server and fetch back information that I can display in a visual format. I have included a download ZIP for this that includes the PHP code, styles and icons used.

The full package includes a stylesheet and icons, see the archived file at the bottom of this post.

Example usage below;

<link href="ts3.css" rel="stylesheet" type="text/css" media="screen" />

<?php
	//Include the TS3 Connection Class
	require('ts3.class.php');

	//Init the class, with out IP, Port, Virtual Server
	$TS3 = new Teamspeak3('0.0.0.0', '10011', '1');

	//Send the commands we want data from.
	$rawData = $TS3->fetchRawCommand(array("clientlist", "serverinfo", "channellist"));

	//Output the display
	echo $TS3->outputDisplay($TS3->sortChannels($TS3->formatChannelData($rawData)), $TS3->formatPlayersArray($rawData));
?>
