求解答

程序代碼

//awork
$ws = new Worker("websocket://0000:2346");
define('Heartbeat',55);
$ws->count = 1;
$ws->uidConnections = array();

    Timer::add(1,function ()use($ws){

                $connection->close();
            }
        }

    });
    $text_worker = new Worker('Text://0000:5656');

            }
        }
        echo $mid;//這里有數(shù)據(jù)，下面報錯
        global $text_worker;
        $text_worker->onMessage = function($connection, $mid)
        {
            $connection->send($mid);
            echo $mid;
        };
    }
};
//bwork
$ws2->onMessage = function($connection, $data)

    global $ws2;
    $connection->lastMessageTime = time();
    if(!isset($connection->mid))
    {
        if(intval($data))

            $ws2->midConnections[$connection->mid] = $connection;
        }else{
            echo  $connection->mid.$data;
        }
        return ;
    }else{
        $buffer= $connection->mid;
        echo  $connection->mid.$data;
        $client = stream_socket_client("tcp://0000:5656");
// text 協(xié)議為字符串末尾加一個換行符 \n
        echo $data;
        fwrite($client, $data."\n");
    }
