销毁会话不起作用

Question

嗨我创建session并希望在1分钟后销毁它，如果用户根据代码不执行任何操作，它应该显示我在一分钟后打印的消息，但它显示什么都不知道为什么？

这是我的代码

  session_start();
$_SESSIONlogin_user = 'abc';
$_SESSION['USER']['login_email'] = 'abc@example.com';
$_SESSION['USER']['login_phone'] = '9876543210';



 if (isset($_SESSION['USER']['login_email'])) {

    $_SESSION['start'] = time();
    $_SESSION['expire'] = $_SESSION['start'] + (1 * 60);


     $now = time();
     if ($now > $_SESSION['expire']) {

            session_destroy();
             header('Location: dev.ludhianalive.com');
            echo "Your session has expired! <a href='#myModal'>Login here</a>";
            exit;
        }


 }

您的问题是，您在之前>检查过期时间是否过去时，将未来的到期时间设置为1分钟。因此，到期时间总是在将来。

您应该对支票到期时间以及设定到期时间的代码进行重新排序。

此外，session_destroy()不会按预期删除用户的数据。在我已包含的documentation for session_destroy中有一个完整的删除会话以记录用户的示例。

session_start();
$_SESSION['login_user'] = 'abc';
$_SESSION['USER']['login_email'] = 'abc@example.com';
$_SESSION['USER']['login_phone'] = '9876543210';

if (isset($_SESSION['USER']['login_email'])) {
    $now = time();
    if (isset($_SESSION['expire']) && $now > $_SESSION['expire']) {
        // Unset all of the session variables.
        $_SESSION = array();

        // If it's desired to kill the session, also delete the session cookie.
        // Note: This will destroy the session, and not just the session data!
        if (ini_get("session.use_cookies")) {
            $params = session_get_cookie_params();
            setcookie(session_name(), '', time() - 42000,
                $params["path"], $params["domain"],
                $params["secure"], $params["httponly"]
            );
        }

        // Finally, destroy the session.
        session_destroy();

        header('Location: dev.ludhianalive.com');
        echo "Your session has expired! <a href='#myModal'>Login here</a>";
        exit;
    }
    $_SESSION['start'] = $now;
    $_SESSION['expire'] = $_SESSION['start'] + (1 * 60);
}
