在 GatewayWorker 下使用 GateWay::sendToAll($cmd,$client_id_array); 傳送資料出現錯誤。

public static function encode($data)
    {
        $flag = (int)is_scalar($data);
        if (!$flag) {
            $data = serialize($data);
        }
        $ext_len     = strlen($data);**<-- $data 是 Array;****

        $package_len = self::HEAD_LEN + $ext_len + strlen($data);
        return pack("NCNnNnNCnN", $package_len,
            $data, $data,
            $data, $data,
            $data, $data,
            $flag, $data,
            $ext_len) . $data . $data;
    }
