CI和简单的PHP之间的连接阅读$ _SESSION

Question

我试图将一个论坛（在Codeigniter中创建）到一个网站（简单的PHP >>>没有框架使用）。

为了自动登录论坛，当我在我的网站登录时，我需要使用论坛的功能，它需要2个参数$ username和$ password。

我已经在我的网站上有$ _SESSION这个信息（用户名和密码）。

如何从论坛读取$ _SESSION（正如我之前所说的基于Codeigniter的），因为我没有权限。

是否有可能性定义2个常量，在论坛的核心/配置中的某个地方，从$ _SESSION中保存这些细节，以便从论坛内的任何位置访问？

我知道CI的会话与$ _SESSION不同，所以请帮助我更实际一些，以解决我的问题。

谢谢。

如果谁想要做2.0.2

本地会话就在native_session.php文件复制到您的应用程序/库/并将其重命名为Session.php

然后更改类名称和构造函数名称到CI_Session

还添加以下，那么它应该工作正常。

function sess_destroy() 
{ 
    $this->destroy(); 
} 

或

<?php if (! defined('BASEPATH')) exit('No direct script access allowed');
