在上面的例子上，我新增了 Server.php 和 Client.php 用于消息轉(zhuǎn)發(fā)
1.Events.php 調(diào)用 Server 方法? (因為Events里面是靜態(tài)的，不太會用，所以新建了一個類)
2.Server方法連接的時候創(chuàng)建AsyncTcpConnection客戶端連接其他的服務(wù)端
3.客戶端收到消息后通過Server發(fā)送給網(wǎng)頁
?4.網(wǎng)頁發(fā)送消息給server, server用AsyncTcpConnection發(fā)送給其他服務(wù)端

Events.phppublic static function onMessage($client_id, $data)
{
    $_SESSION->onMessage($client_id, $data);
}

public static function onConnect($client_id)
{
    $_SESSION = $client_id;
    $_SESSION = new Server();
    $_SESSION->onConnect($client_id);
}
?
Server.php<?php

public function onConnect($client_id)
{
    $serverIp = '***.***.***.***';
    $serve = "ws://$serverIp:9999";
    $_SESSION = new AsyncTcpConnection($serve);
    $_SESSION = new Client($client_id);
    $_SESSION->serveClientId = $client_id;
    $_SESSION->serverIp = $serverIp;
    $_SESSION->onConnect = array($_SESSION, 'onConnect');
    $_SESSION->onMessage = array($_SESSION, 'onMessage');
    $_SESSION->onError = array($_SESSION, 'onError');
    $_SESSION->onClose = array($_SESSION, 'onClose');
    $_SESSION->onError = array($_SESSION, 'onError');
    $_SESSION->connect();
}
public function onMessage($client_id, $data)
{
    $_SESSION->onRecv($data);
}
?
Client.phpfunction onConnect($con)
{
    $this->mCon = $con;
}
public function onRecv($data)
{
    var_dump($this->mCon);
}

?
請問在 Client.php? 里面 var_dump($this->mCon)為什么是NULL呢？
