每当我进入一个页面，即登录页面或任何其他页面时，我都想将页面的名称保存在一个$_SESSION变量中。

登录页面：

<?php
    session_start();
    $_SESSION['page'] = 'login.htm';    
?>

它仅适用于登录页面，不会覆盖其他页面，例如主页：

<?php
    session_start();
    $_SESSION['page'] = "home.htm"; 
?>

我需要会话变量'page'来保存我的最后一页，有人可以帮忙吗？

Why not just use $_SERVER['HTTP_REFERER']? This will give you the previous page in PHP, without having to add anything to sessions.

If all you need is default "back" functionality you should let the browser handle it.

If what you want is something to be used as a breadcrumb following some internal order (or path in a tree) my advice is to let each page "know" the path that leads to it.

If you really need to know from what page the user came from save it to a previous variable before you write over the current variable.

// Make sure user didnt just refresh the page
if ($_SESSION["current"] !== "currentPage.php") {
  $_SESSION["previous"] = $_SESSION["current"];
  $_SESSION["current"] = "currentPage.php";
}

当您导航到新页面时，首先检索保存的“后退”变量（并在后退链接/面包屑或其他内容中使用它），然后用当前页面覆盖会话“后退”变量，以便为下一个页面做好准备移动 =)

You're using different keys.. 'page' and 'back'.
