我写了个socket server,需要能共享父进程的$gsocks给子进程,但好像不能做到,我应该怎么做才能共享变量?

补充,额,memcache或者redis存的是字符串之类的把,我如何共享我问题代码中的socket res句柄?

代码如下:

服务端的:

<code><?php

$gsocks = array();


$pid = pcntl_fork();

switch ($pid) {
    case -1:
        #fail
        break;

    case 0:
        for(;;){
            sleep(1);
            echo "C";
            var_dump($gsocks);###     这里一直输出空数组,那么应该如何共享内存呢?
            if (count($gsocks) == 0) continue;
            
            $gsock = $gsocks[rand(0,count($gsocks)-1)];
            $msg = time()." You are a lucky man \n";
            socket_write($gsock, $msg, strlen($msg));
        }
        #i am child
        break;

    default:
        //确保在连接客户端时不会超时
        set_time_limit(0);
        //设置IP和端口号
        $address = "127.0.0.1";
        $port = 2046; //调试的时候,可以多换端口来测试程序!
        $sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die("socket_create() 失败的原因是:" . socket_strerror(socket_last_error()) . "/n");
        //阻塞模式
        socket_set_block($sock) or die("socket_set_block() 失败的原因是:" . socket_strerror(socket_last_error()) . "/n");
        //绑定到socket端口
        $result = socket_bind($sock, $address, $port) or die("socket_bind() 失败的原因是:" . socket_strerror(socket_last_error()) . "/n");
        //开始监听
        $result = socket_listen($sock, 4) or die("socket_listen() 失败的原因是:" . socket_strerror(socket_last_error()) . "/n");
        do { // never stop the daemon
            //它接收连接请求并调用一个子连接Socket来处理客户端和服务器间的信息
            $msgsock = socket_accept($sock) or  die("socket_accept() failed: reason: " . socket_strerror(socket_last_error()) . "/n");

            //读取客户端数据
            //socket_read函数会一直读取客户端数据,直到遇见\n,\t或者\0字符.PHP脚本把这写字符看做是输入的结束符.
            $buf = socket_read($msgsock, 8192);
//            echo "Received msg: $buf   \n";

            //数据传送 向客户端写入返回结果
            $msg = "welcome \n";
            socket_write($msgsock, $msg, strlen($msg)) or die("socket_write() failed: reason: " . socket_strerror(socket_last_error()) ."/n");
            //一旦输出被返回到客户端,父/子socket都应通过socket_close($msgsock)函数来终止

            $gsocks[] = $msgsock;

            if ($buf == "stop") {
                break;
            }

        } while (true);

        foreach ($gsocks as $gsock) {
            socket_close($gsock);
        }

        socket_close($sock);
    #parent
}

客户端的:

<code><?php  
/** 
 * File name:client.php 
 * 客户端代码 
 *  
 * @author guisu.huang 
 * @since 2012-04-11 
 */  
set_time_limit(0);  
  
$host = "127.0.0.1";  
$port = 2046;  
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)or die("Could not create  socket\n"); // 创建一个Socket  
   
$connection = socket_connect($socket, $host, $port) or die("Could not connet server\n");    //  连接  
socket_write($socket, "hello socket") or die("Write failed\n"); // 数据传送 向服务器发送消息  
while ($buff = socket_read($socket, 1024, PHP_NORMAL_READ)) {  
    echo("Response was:" . $buff . "\n");  
}  
socket_close($socket);  </code>

memcacheredis之流即可搞定。
