Answer 1

这是因为会话没有被破坏。我们可以使用这些函数取消设置会话。

session_destroy();
$_SESSION = [];

现在它可以工作了。你的代码应该是这样的

// (A) START SESSION
session_start();

 // (B) LOGOUT REQUEST
if (isset($_POST['logout'])) { unset($_SESSION['user']); 
 session_destroy(); $_SESSION = []; }

 // (C) REDIRECT TO LOGIN PAGE IF NOT LOGGED IN
 if (!isset($_SESSION['user'])) {
     header("Location: Login.php?Page=".$PageToEdit);
     die();
 }
