php - 无法结束 PHP session

Question

好的，所以我有以下代码来回显我已经设置的一些 session 变量。(它们像预期的那样回显。)

(索引.php)

<?php session_start();?>
Username: <?php echo $_SESSION['username']; ?><br>
Password(encrypted): <?php echo $_SESSION['password']; ?><br>
ThemeColor: <?php echo $_SESSION['themecolor']; ?><br>

---

我有这段代码，我试图用它来结束 session ，但是当我运行上面的代码时，变量仍然回显，所以 session 仍然有效

(注销.php)

<?php
session_start();
session_unset();
session_destroy();
?>

你能告诉我我做错了什么吗？

直接来自 PHP documentation :

<?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();
?>
