一切工作正常,但什麼我想要做的是有用戶名發送到服務器,所以如果有人連接,它顯示他們的用戶名而不是IP。只是想知道如何去做這件事。提前致謝!

如果您使用其他人的腳本,它總是引用,你發現它很好的做法:d ...

編號:http://www.sanwebe.com/2013/05/chat-using-websocket-php-socket

我一直在用這個腳本玩弄藏漢,這是真正的好:d

所以,在我希望會回答你的問題......

你可以做什麼,是在websocket.onopen功能發送用戶名(格式化,使服務器能夠理解當新的用戶名發送),然後改變server.php代碼,然後通知新用戶的每個人......因此,這將是這個樣子:

Chat.php改變

websocket.onopen = function(ev) { 
     $('#message_box').append("<div class=\"system_msg\">Connected!</div>"); 
     //send username to server 
     var msg = { 
      newuser: '<?php echo $user->data()->username; ?>' 
     }; 
     websocket.send(JSON.stringify(msg)); 
    } 

Server.php改變

if (in_array($socket, $changed)) { 
    $socket_new = socket_accept($socket); 
    $clients[] = $socket_new; 

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

    //remove the code that sends the IP 
    //socket_getpeername($socket_new, $ip); 
    //$response = mask(json_encode(array('type'=>'system', 'message'=>$ip.' connected'))); 
    //send_message($response); 

    $found_socket = array_search($socket, $changed); 
    unset($changed[$found_socket]); 
} 

..

foreach ($changed as $changed_socket) { 

    while(socket_recv($changed_socket, $buf, 1024, 0) >= 1) 
    { 
     $received_text = unmask($buf); 
     $tst_msg = json_decode($received_text); 
     //check if the 'newuser' has been recieved, otherwise send a normal message 
     if(isset($tst_msg->newuser)) { 
      $response = mask(json_encode(array('type'=>'system', 'message'=>$tst_msg.' joined the room'))); 
      send_message($response); 
     } else { 
      $user_name = $tst_msg->name; 
      $user_message = $tst_msg->message; 
      $user_color = $tst_msg->color; 

      $response_text = mask(json_encode(array('type'=>'usermsg', 'name'=>$user_name, 'message'=>$user_message, 'color'=>$user_color))); 
      send_message($response_text); 
     } 

     break 2; 
    } 

希望這會有幫助:D
