标签: php javascript sockets ping minecraft

我正在创建这个列出Minecraft服务器的网站。基本上我正试图在显示它们时ping所有这些服务器。使用php解决这个问题对我来说并不能解决它,ping所有服务器需要时间,而且我知道javascript可以同时执行多个“ping”。我该怎么做?

我现在使用的PHP代码:

class minecraft_server
{
    private $address;
    private $port;

    public function __construct($address, $port = 25565){
        $this->address = $address;
        $this->port = $port;
    }

    public function get_ping_info(&$info){

        $starttime = microtime(true);
        $socket = @fsockopen($this->address, $this->port, $errno, $errstr, 1.0);
        $stoptime  = microtime(true);
        $ping = round(($stoptime-$starttime)*1000);

        if ($socket === false){
            return false;
        }

        fwrite($socket, "\xfe\x01");

        $data = fread($socket, 256);

        if (substr($data, 0, 1) != "\xff"){
            return false;
        }

        if (substr($data, 3, 5) == "\x00\xa7\x00\x31\x00"){
            $data = explode("\x00", mb_convert_encoding(substr($data, 15), 'UTF-8', 'UCS-2'));
        }else{
            $data = explode('§', mb_convert_encoding(substr($data, 3), 'UTF-8', 'UCS-2'));
        }

        if (count($data) == 3){
            $info = array(
                'version'       => '1.3.2',
                'motd'          => $data[0],
                'players'       => intval($data[1]),
                'max_players'   => intval($data[2]),
                'ping'          => $ping
            );
        }else{
            $info = array(
                'version'       => $data[0],
                'motd'          => $data[1],
                'players'       => intval($data[2]),
                'max_players'   => intval($data[3]),
                'ping'          => $ping
            );
        }

        return true;
    }
}

你用以下方法调用该函数:

$server = new minecraft_server(IP, PORT);
if (!$server->get_ping_info($info)){
    echo "Offline";
}else{
    print_r($info);
}

我如何在javascript中创建类似的东西?

在你的位置,我可能会设置一个脚本,当被调用时,ping所选服务器并打印一个可解析的结果,然后每当需要发送ping时使用Ajax调用该脚本。
