Пример:
//require_once "MinecraftStatus.class.php";
$ip = "127.0.0.1"; // IP адрес сервера Minecraft
$qport = 25565; // порт сервера Minecraft
$Server2 = new MinecraftStatus($ip, $qport); 
$online = $Server2->Online; // сервер онлайн (bool: true / false)
$cur = $Server2->CurPlayers; // количество онлайн игроков на сервере
$max = $Server2->MaxPlayers; // максимум игроков на сервере
$motd = $Server2->MOTD; // MOTD сервера
