具有多个会话的session_destroy() [英] session_destroy() with multiple sessions

问题描述

我的页面上有3个登录表单，单击注销将销毁所有会话并将其全部注销.我知道session_destroy()会销毁与当前会话相关的所有数据，但是我可以给它一个参数还是有什么办法指定要销毁的会话?我已经尝试过在没有session_destroy的情况下使用unset，但是它不会注销用户

I have 3 login forms in my page, clicking logout is destroying all the sessions and logging them all out. I know that session_destroy() destroys all the data associated with the current session but could i give it a parameter or is there any way to specify which session to destroy? I have tried using unset without the session_destroy but it won't logout the user

代码已

<?php
    if(isset($_GET['auth'])){
        if($_GET['auth']=='parent'){
        session_name('parent');
        session_start();
            if(isset($_SESSION['parent']))
                unset($_SESSION['parent']); 
                session_destroy();
    }}
    if(isset($_GET['auth'])){
        if($_GET['auth']=='employee'){
        session_name('employee');
        session_start();
            if(isset($_SESSION['employee']))
                unset($_SESSION['employee']); 
                session_destroy();
    }}
    if(isset($_GET['auth'])){
        if($_GET['auth']=='student'){
        session_name('student');
        session_start();
            if(isset($_SESSION['student']))
                unset($_SESSION['student']); 
                session_destroy();
    }}

    header("Location: login.php");
    ?>

我添加了session_name来获得不同的会话，我可以销毁该会话，但是在同一页面中不能有多个会话！

I have added session_name to get different sessions, i am able to destroy the session but i can't have multiple sessions in the same page!

推荐答案

请使用session_start();在页面顶部一次.成功登录后，请检查所有已设置的会话，例如您的情况.

Please use session_start(); once at the top of the page. After successful login, please check all the sessions that is set, for example in your case.

$_SESSION['parent'];
$_SESSION['employee'];
$_SESSION['student'];

session_name('');将覆盖上一个会话的名称，因此您不必在此处使用session_name.如果您检查特定会话的值或会话名称是否存在未设置($ _SESSION('your_session_key'));希望它能工作.谢谢

session_name(''); will override the previous session's name, so you don't have to use session_name here. If you check there is a value for specific session or the session name is exist unset($_SESSION('your_session_key')); Hope it will work. Thanks
