CodeIgniter：unset所有userdata，但不会销毁会话 [英] CodeIgniter: unset all userdata, but not destroy the session

问题描述

有没有办法在会话中取消设置所有用户数据，而不必使用会话销毁？我试图记录我的用户，需要取消所有userdata一次一个。跟踪在会话中设置的所有可能的用户数据变得冗长乏味。

Is there a way to unset ALL userdata in a session without having to use session destroy? I'm trying to log my user out and need to unset all userdata one at a time. It's becoming tedious to keep track of all possible userdata set in session. I just want to unset everything that might have been set in userdata.

推荐答案

这很简单！

 $this->session->unset_userdata('some_name');

或

 $array_items = array('username' => '', 'email' => '');
 $this->session->unset_userdata($array_items);

我希望这有助于！

strong> Edit：看起来你实际上没有跟踪会话中的任何东西（有点奇怪？）。你可以调用这个函数我写道：

It looks like you actually don't keep track of anything in your session (kind of strange?). You could call this function I wrote up:

function unset_only() {
    $user_data = $this->session->all_userdata();

    foreach ($user_data as $key => $value) {
        if ($key != 'session_id' && $key != 'ip_address' && $key != 'user_agent' && $key != 'last_activity') {
            $this->session->unset_userdata($key);
        }
    }
}

假设您使用默认的CI会话设置。
