socket - php pthreads主线程如何获取到子线程的scoket资源？

php pthreads主线程如何获取到子线程的scoket资源？
最近公司要做的一个业务是，要用amqp的consume方法监听队列，同时与多个终端保持连接，一旦队列里有消息就马上下发给终端，不能有延迟，
我想到的是只能用线程来做，如果用多进程来实现，socket资源是不能共享的，但是现在用了pthreads 扩展也不行，从主线程中无法获取到子线程中的连接，大侠们请教下怎么弄

<code>  <?php class PrintServer extends Thread{
    public  $connections = array();
    public function __construct() {
        $this->connections = array();
    }
    public function run(){
        $connections = array();
        //监听端口
        $PORT = 8888;
        $sock = socket_create_listen($PORT);
        if (!$sock) {
            exit(1);
        }
//不阻塞
        socket_set_nonblock($sock);
        while (true) {
        //    $readfds = array_merge($this->connections, array($sock));
            $readfds = array_merge($connections, array($sock));
            $writefds = array();
            //选择一个连接，获取读、写连接通道
            $e= null;
            $flag = socket_select($readfds, $writefds, $e, $t = 5);
            if ($flag) {
                foreach ($readfds as $rfd) {
                    if ($rfd == $sock) {
                        //接受客户端连接
                        $newconn = socket_accept($sock);
                        $i = (int)$newconn;
                        //将当前客户端连接放如socket_select选择
                        $connections[$i] = $newconn;
                        //输入的连接资源缓存容器
                        $writefds[$i] = $newconn;
                        var_dump($connections);
                        $this->connections = $connections;

                        echo "Welcome to the PHP Chat Server!\n";
                        continue;
                    }
                }
            }
