Nur einen Channel erstellen TeamSpeak3 PHP

Hey liebe Elitepvpers Community,
Habe im Internet ein Script f�r einen TeamSpeak3 Server gefunden mit dem man �ber eine Homepage TeamSpeak3 Channel erstellen kann. Nun meine Frage, wie kann ich das so einstellen das jeder nur einen Channel erstellen kann?
Code:
<?php session_start(); ?>
<?php
	if(!isset($_SESSION['ts3_last_query']))
    $_SESSION['ts3_last_query'] = microtime(true);
	
	if($_SESSION['ts3_last_query'] >= microtime(true))
    die('You Need Wait 10 Seconds To Create Channel Again');
	
	$_SESSION['ts3_last_query'] = microtime(true)+10.0;
	
	date_default_timezone_set('America/Argentina/Buenos_Aires'); //Change Here!
	require_once("libraries/TeamSpeak3/TeamSpeak3.php");
	include 'data/config.php';
	
 
    function getClientIp() {
        if (!empty($_SERVER['HTTP_CLIENT_IP']))
            return $_SERVER['HTTP_CLIENT_IP'];
        else if(!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
            return $_SERVER['HTTP_X_FORWARDED_FOR'];
        else if(!empty($_SERVER['HTTP_X_FORWARDED']))
            return $_SERVER['HTTP_X_FORWARDED'];
        else if(!empty($_SERVER['HTTP_FORWARDED_FOR']))
            return $_SERVER['HTTP_FORWARDED_FOR'];
        else if(!empty($_SERVER['HTTP_FORWARDED']))
            return $_SERVER['HTTP_FORWARDED'];
        else if(!empty($_SERVER['REMOTE_ADDR']))
            return $_SERVER['REMOTE_ADDR'];
        else
            return false;
    }
	
    $connect = "serverquery://".$USER_QUERY.":".$PASS_QUERY."@".$HOST_QUERY.":".$PORT_QUERY."/?server_port=".$SERVER_PORT."";
    $ts3 = TeamSpeak3::factory($connect);
    $ts3->execute("clientupdate", array("client_nickname" => $NICK_QUERY));
    $FLAG = false;
	
    foreach ($ts3->clientList(array('client_type' => '0', 'connection_client_ip' => getClientIp())) as $client) {
        $clientuid = $client->client_unique_identifier;
		$client_nickname = $client->client_nickname;
		$client_clid = $client->clid;
        $FLAG = true;
        break;
    }
    if (!$FLAG){
        echo "<p><b>".$lang['f_connectts'].".</b></p><br/>";
        header("refresh: 10; url = ./");
        die;  
    }
 
	if (isset($_POST["create"])) {
		
		$channelname = $_POST['channelname'];
		$password = $_POST['password'];
		$unixTime = time();
		$realTime = date('[Y-m-d]-[H:i]',$unixTime);
		$channel_admin_group = 14; 

		try
		{
			$cid1 = $ts3->channelCreate(array(
			"channel_name" => "$channelname",
			"channel_password" => "$password",
			"channel_flag_permanent" => "1",
			"channel_description" => '[center][b][u]'.$channelname.'[/u][/b][/center][hr][b][list][*]Date: '.$realTime.'[*]Owner: ' . $client_nickname . '[/list][/b]',
			"channel_order" => "$order"));
			
			$ts3->clientGetByUid($clientuid)->setChannelGroup($cid1, $channel_admin_group);
			$ts3->clientMove($client_clid, $cid1);
			
		}
		catch(Exception $e)
		{
			echo "Error (ID " . $e->getCode() . ") <b>" . $e->getMessage() . "</b>";
		}
