如何在PHP中创建websockets服务器

Question

是否有任何教程或指南显示如何在PHP中编写一个简单的websockets服务器？我试过在谷歌上寻找它，但我找不到很多。我发现phpwebsockets但它现在已经过时，不支持最新的协议。我自己尝试更新它，但似乎没有用。#!/php -q<?php  /*  >php -q server.php  */error_reporting(E_ALL);set_time_limit(0);ob_implicit_flush();$master  = WebSocket("localhost",12345);$sockets = array($master);$users   = array();$debug   = false;while(true){  $changed = $sockets;  socket_select($changed,$write=NULL,$except=NULL,NULL);  foreach($changed as $socket){    if($socket==$master){      $client=socket_accept($master);      if($client<0){ console("socket_accept() failed"); continue; }      else{ connect($client); }    }    else{      $bytes = @socket_recv($socket,$buffer,2048,0);      if($bytes==0){ disconnect($socket); }      else{        $user = getuserbysocket($socket);        if(!$user->handshake){ dohandshake($user,$buffer); }        else{ process($user,$buffer); }      }    }  }}//---------------------------------------------------------------function process($user,$msg){  $action = unwrap($msg);  say("< ".$action);  switch($action){    case "hello" : send($user->socket,"hello human");                       break;    case "hi"    : send($user->socket,"zup human");                         break;    case "name"  : send($user->socket,"my name is Multivac, silly I know"); break;    case "age"   : send($user->socket,"I am older than time itself");       break;    case "date"  : send($user->socket,"today is ".date("Y.m.d"));           break;    case "time"  : send($user->socket,"server time is ".date("H:i:s"));     break;    case "thanks": send($user->socket,"you're welcome");                    break;    case "bye"   : send($user->socket,"bye");                               break;    default      : send($user->socket,$action." not understood");           break;  }}function send($client,$msg){  say("> ".$msg);  $msg = wrap($msg);  socket_write($client,$msg,strlen($msg));}如果的代码有什么问题你可以帮我解决吗？Firefox中的Concole说Firefox can't establish a connection to the server at ws://localhost:12345/.

据我所知，Ratchet是目前最好的PHP WebSocket解决方案。而且由于它是开源的，你可以看到作者是如何使用PHP构建这个WebSocket解决方案的。
