Question

我正在编写PHP套接字服务器，这里显示的是导致错误的部分。我发现 socket_recv（） 导致问题，它只允许一台计算机连接。但是，如果我注释掉 socket_recv ，那么它的工作正常。但我必须在套接字服务器中接收数据。帮我找出解决方案。还请指出任何错误的代码。 JQuery部分工作正常，因此没有在这里打印。

<?php
    set_time_limit(0);

    $host = '172.28.4.5';
    $port = 10000;
    $null = NULL;

    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
    socket_bind($socket, $host, $port);
    socket_listen($socket);
    $clients = array($socket);

    while(true) {

       $new_socket = socket_accept($socket);//Accepting new connection/socket/client if any
       $clients[] = $new_socket;//Adding the new client/socket/connection to client array

       $header = socket_read($new_socket, 1024);
       perform_handshaking($header, $new_socket, $host, $port);

       /* If I want to notify if new connection is established**/
      socket_getpeername($new_socket, $ip);
      $message = "Welcome to WebSocket $ip";

      $array = array(
              'message' => $message
              );
      $message = mask(json_encode($array));     
      write_to_socket($message);

      $found = array_search($socket, $clients);
      unset($clients["$found"]); 

      //Going through each client
      foreach($clients as $client) {

             //Getting messages with loop how many packages for each client has
             while(socket_recv($client, $buf, 1024, 0) >= 1) {

                      $array = json_decode(unmask($buf));
                      print_r($array);
              }
       }
   }
 }
?>

似乎是这样代码错了

    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    socket_set_option($socket, SOL_SOCKET, SO_REUSEADDR, 1);
    socket_bind($socket, $host, $port);
    socket_listen($socket);
    //$clients = array($socket);   <---- here

    while(true) {

似乎您将侦听的套接字添加到数组中，您不应该从侦听的套接字接收数据。

PHP：套接字服务器被socket_recv（）中断
