php - 完全销毁 session 的最佳方法 - 即使浏览器未关闭

Question

够不够

session_start();   //  Must start a session before destroying it

if (isset($_SESSION))
{
    unset($_SESSION);
    session_unset();
    session_destroy();
}

当用户从菜单中选择注销，但没有退出浏览器时？我想完全删除所有存在的 session 和 $_SESSION

根据manual ，还有更多工作要做:

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.

手动链接有一个关于如何做到这一点的完整工作示例。从那里偷来的:

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// 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();
?>
