我正在尝试将一个论坛（在Codeigniter中创建）集成到一个网站中（简单的php>>>没有使用框架）。
为了自动登录论坛，当我登录我的网站时，我需要使用论坛的一个功能，该功能需要两个参数$username和$password。
我已经从我的网站上获得了这些信息（用户名和密码），在$_SESSION中。
我如何从论坛上阅读$_SESSION（正如我在基于Codeigniter之前所说的），因为，我没有访问权限。
是否有可能在论坛的核心/配置中定义2个常量，以保存$_SESSION中的这些详细信息，以便从论坛内的任何地方访问？
我知道CI的会话与$_SESSION不同，所以请帮我做一些更实用的事情，以解决我的问题。
谢谢。

对于那些想用2.0.2 进行本机会话的人来说
只需将native_session.php文件复制到您的应用程序/librarys/并将其重命名为session.php
然后将类名和构造函数名更改为CI_Session
还要添加以下内容，那么它应该可以正常工作。
function sess_destroy()
{
$this->destroy();
}
