<?php // load framework files
require_once("ts3/libraries/TeamSpeak3/TeamSpeak3.php");
require_once("extra/common.php");

    error_reporting(E_ALL);
    
    try
    {
            $ts3_VirtualServer = TeamSpeak3::factory($serverinfo);

            foreach($ts3_VirtualServer->clientList()as $ts3_Client)
            {
                    if($ts3_Client['client_type']) continue;
                    $query = "
                        SELECT
                        username
                        FROM users
                        WHERE username = username
                    ";
                    try
                    {
                        $stmt = $db->prepare($query);
                        $result = $stmt->execute();
                    }
                    catch(PDOException $ex)
                    {
                        die("Failed to run query: " . $ex->getMessage());
                    }
                    $rows = $stmt->fetchall();
                    
                    foreach($rows as $row)
                    {
                        $driver = $ts3_Client['client_nickname'];
                        if($driver == $row['username'])
                        {
                            $array = $ts3_VirtualServer->execute("servergroupclientlist", array("sgid" => 13, "-names"))->toAssocArray("cldbid");
                            if(in_array($driver, $array) == true) continue;
                            $continue = true;
                            foreach(explode(",", $ts3_Client["client_servergroups"]) as $sgid)
                            {
                                if($sgid == 13) $continue = false;
                            }
                            if($continue == false) continue;
                            $ts3_VirtualServer->clientListReset();
                            $ts3_VirtualServer->serverGroupClientAdd("13", $ts3_Client["client_database_id"]);
                            echo ("Set User as Verified");
                        }
                        elseif($driver !== $row['username'])
