PHP

Question

登录后我的网站上有一个 link，它指向 "index.php?logout=yes"，然后在我的 index.php 中有以下代码：

if ($_GET['logout'] == "yes") {
    session_unset();
    unset($_SESSION);
    session_destroy();
    echo "<meta http-equiv='refresh' content='0;url=index.php'>";
    $_SESSION = array();
    $_SESSION = [];
}

知道为什么它会让您保持登录状态但不会结束会话吗？

Answer 1

这是你的第一行代码吗index.php如果是使用 header('Location: /'); 而不是刷新的元标记

Answer 2

请检查：session_destroy

In order to kill the session altogether, like to log the user out, the session id must also be unset. If a cookie is used to propagate the session id (default behavior), then the session cookie must be deleted. setcookie() may be used for that.

试试这个

session_unset(); //or unset($_SESSION);
session_destroy();
session_commit(); // or session_write_close();
setcookie(session_name(),'',0,'/');
session_regenerate_id(true);

header('location: index.php');

Answer 3

注销后，将用户重定向到主页（例如）

并且始终在使用之前启动会话

<php 
session_start();   
if ($_GET['logout'] == "yes") {
   session_unset();
   session_destroy();
   session_write_close();
   setcookie(session_name(),'',0,'/');
   session_regenerate_id(true);
   header('location: index.php');
}

Answer 4

public 函数注销() {

    $this->session->set_userdata(array(
        'user_id'       => '',
        'fname'         => '',
        'lname'         => '',
        'gender'        => '',
        'username'      => '',
        'user_comp_id'  => '',
        'user_role'     => '',
        'validated'     => false,
        'plan_name'     => '',
        'plan_restriction' => '',
        'module_leave_bank' => '',
        'module_custom_logo' => '',
        'module_bulk_import' => '',
        'module_custom_rules' => '',
        'module_reports_download' => '',
        'module_integrations' => '',
        'module_chat_support' => '',
        'module_phone_support' => '',
        'users_limit'       => '',
        'leave_policies_limit' => '',
        'ous_limit'         => '',
        'sub_ous_limit'     => '',
        'leave_requests_limit' => '',
        'holidays_limit'    => '',
        'users_count'       => '',
        'leave_policies_count' => '',
        'ous_count'         => '',                       
    ));
    $cookies_id = $this->input->cookie('ci_session', TRUE);
    // $this->db->delete('user_logged_in',array('cookie' => $cookies_id)); // delete the cookies in database
    $this->session->sess_destroy();

    redirect('login', 'refresh');
}

PHP - 无法结束会话

PHP - Can't end session
