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，它需要两个参数 $username 和 $password。

我已经从我的网站 $_SESSION 中获得了这些信息（用户名和密码）。

我如何从论坛中读取 $_SESSION（正如我在基于 Codeigniter 之前所说的那样），因为我无法访问它。

是否有可能在论坛的核心/配置中的某处定义 2 个常量，以保存来自 $_SESSION 的这些详细信息，以便从论坛内的任何地方访问？

我知道来自 CI 的会话与 $_SESSION 不同，所以请帮助我做一些更实际的事情，以解决我的问题。

谢谢。

以防那些想要使用 2.0.2 进行本地会话的人

只需将 native_session.php 文件复制到您的 application/libraries/ 并将其重命名为 Session.php

然后将类名和构造函数名改为CI_Session

还要添加以下内容，它应该可以正常工作。

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

或者

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