如何在CodeIgniter中获取会话超时？

Question

我试图在会话超时前5分钟运行一个功能.我的配置文件中的会话超时设置为7,200.是否可以使用CodeIgniter执行此操作？

我想你正在寻找这样的东西:

$lastActivity = $this->session->userdata('last_activity');

$timeOut = time() - 7200 + 300; // now minus the the session 
                                   // timeout plus 5 minutes

if ($lastActivity <= $timeOut)
{
    /* This runs on or after the "5 minutes before mark", but won't run if the
       session has expired. After the session times out, based on the 
       $config['sess_expiration'] var, it's destroyed, as pointed out by
       coolgeek. */

    // ... Do some stuff
}

您可能希望在钩子内部运行它(请参阅此处的钩子文档),以便它在运行控制器之前或之后的每个页面加载上运行,具体取决于您尝试执行的操作.
