php写tcp服务器怎么样？

我看了下php的pctnl库好像支持多进程而且还支持select、epoll等IO模型，不知道php做的服务端效果怎么样，有谁试过吗？

这个不是php的强项啊。

用socket 可以写值守程序的。

    不见得啊 它既然有这个功能 肯定有它的存在价值 我希望能把它发挥出来

可以应付普通应用，php的有些网络库也引入了libevent

有两问？
一、 一个php的版webgame server 可不可以fork多个进程去监听同一个端口呢，如果可以大概能撑多少个人同时在线（进程不挂掉就ok）？
二、如果采用单一进程绑定事件的方式，能撑多少？
有木试过？

可以fork多个进程
<?php   
$socket = stream_socket_server("tcp://0.0.0.0:8000", $errno, $errstr);
if (!$socket)
throw new Exception("$errstr ($errno)<br />\n");

// 生成子进程
$pid = pcntl_fork();
if ($pid == -1) {
   die('could not fork');
} else if ($pid) {
   loop($socket , 1);
   pcntl_wait($status);
} else {
   loop($socket , 2);
}


function loop($socket , $id) {
    while ($conn = stream_socket_accept($socket)) {
            /*
            $data = '';
            while(($c=fgetc($read_sock))!==false && $c!="\0" && $c!="\n" && $c!="\r"){
                $data .= $c;
            }*/
            fwrite($conn, "Server ID :   $id , hello!\n");
            fclose($conn);
    }

    fclose($socket);
}


另外你可以试试php异步IO+消息列队+producer/consumer模型，至于可用性不敢保证，性能方面应该不会太差，之前是有PHP的web server的开源产品。

用swoole把，C扩展实现的PHP多线程异步Server。

swoole vs nodejs有人测试过性能吗?

可以使用swoole轻松实现 http://bbs.chinaunix.net/thread-4145582-1-1.html
