php socket编程 读完成后写阻塞

socket tcp php server server端代码 如下：

 client端， 代码如下：  

 如果将server端对client read操作换成循环内部读取，则client会一直处于 wait data状态。  
 有办法让server端循环读的情况下，读完后给client写数据吗  




回复讨论(解决方案)
 
  你这个循环没有错，但是一次数据发送完成就关闭socket连接了，没有循环的必要吧。

 这个只是个demo，实际情况下，client发过来的数据不定长，所以只能循环接收 
 
  

 读循环里面确实不应该用PHP_NORMAL_READ这个选项  
 去掉PHP_NORMAL_READ这个选项也不能解决问题，有解决方法吗  
  
while (true) {    $msg = socket_accept ($socket);               // 接受一个SOCKET    if (!$msg) {        echo "socket_accept() failed:".socket_strerror ($msg)."\n";        break;    }    while (true) {        $command = strtoupper (trim (socket_read ($msg, 1024))); //等待客户端数据        if (!$command) break;        //相关处理，比如直接回显        socket_write ($msg, $command, strlen ($command));    }    socket_close ($msg);    if ($command == "QUIT") //如果收到的是通讯结束        break;}socket_close ($socket);                   // 关闭SOCKET

 我都是用流函数实现的。  
ip = $ip;        $this->port = $port;        //        self::init();        //        $this->createServer();        $this->log('listenning user...');        $this->listenningUser();    }    protected function createServer() {        $errno;        $errstr;        $this->webSocket = stream_socket_server("tcp://" . $this->ip .

 版主好  
 这里我需要读取完client放的数据分析后才能write回client端，你想让client那边发送quit命令结束socket，这个在线上环境不能实现。还有更好的办法吗？多谢各位！！
