//当接收到客户端发来的数据后显示数据并回发到客户端

    //向客户端回发数据  
   if(!isset($connection->uid))
    {
       // 没验证的话把第一个包当做uid（这里为了方便演示，没做真正的验证）
       $connection->uid = $data;
       /* 保存uid到connection的映射，这样可以方便的通过uid查找connection，
        * 实现针对特定uid推送数据
        */
       $ws_worker->uidConnections[$connection->uid] = $connection;
       return $connection->send('login success, your uid is ' . $connection->uid);
    }
    // uid 为 all 时是全局广播
    list($recv_uid, $message) = explode(':', $data);
    // 全局广播
    if($recv_uid == 'all')
    {
        broadcast($message);
    }
    // 给特定uid发送
    else
    {
        sendMessageByUid($recv_uid, $message);
    }
}; 

// 向所有验证的用户推送数据
function broadcast($message)
{
   global $ws_worker;
   foreach($ws_worker->uidConnections as $connection)
   { 
   	    echo '1/';
        $connection->send($message);
   }
}

// 针对uid推送数据
function sendMessageByUid($uid, $message)
{
    global $ws_worker;
    if(isset($ws_worker->uidConnections[$uid]))
    {
        $connection = $ws_worker->uidConnections[$uid];
        $connection->send($message);
    }
} 

// 运行worker
Worker::runAll();
?>

　　可以单独给某个用户发信息，又可以给全部人发信息
