Сценарий на стороне сервера GPS трекера

У меня есть устройство отслеживания GPS, которое я хочу подключить к своему серверу. Я использую PHP SocketServer.class.php. Теперь моя проблема в данных, которые я получаю от отслеживания

)) ±

Но это не так. Вот ссылка на сайт скачать стандартный протокол для устройства. Может кто-нибудь, пожалуйста, покажите мне, где моя вина может быть …

index.php

error_reporting(0);
set_time_limit(0);
ob_implicit_flush();

require_once("SocketServer.class.php"); // Include the File
$server = new SocketServer("154.0.160.80",5522); // Create a Server binding to the given ip address and listen to port 31337 for connections
$server->max_clients = 10; // Allow no more than 10 people to connect at a time
$server->hook("CONNECT","handle_connect"); // Run handle_connect every time someone connects
$server->hook("INPUT","handle_input"); // Run handle_input whenever text is sent to the server
$server->infinite_loop(); // Run Server Code Until Process is terminated.function handle_connect(&$server,&$client,$input)
{
SocketServer::socket_write_smart($client->socket,"String? ","");
}
function handle_input(&$server,&$client,$input)
