PHP session_id 在刷新时永远不会相同 [英] PHP session_id never the same on refresh

问题描述

我试图在某些 php 页面上使用 session_id()，但是每个文件之间的 id 都会发生变化，并且每次刷新页面时都会发生变化.我放置了以下脚本，它应该在重新加载时增加，但它没有.

I am trying to use session_id() on some php pages, but the id changes between every file and it changes everytime i refresh the page. I placed the following script which should increment on ever reload, but it does not.

session_start();
if (!isset($_SESSION['hits'])) $_SESSION['hits'] = 0;
++$_SESSION['hits'];

echo '<p>Session hits: ', $_SESSION['hits'], '</p>';
echo '<p>Refresh the page or click <a href="', $_SERVER['PHP_SELF'],
'">here</a>.';

在我的 php.ini 文件中，我打开了 cookie 并设置了我的 save_path tp '/tmp'.

In my php.ini file, I have cookies turned on as well as set my save_path tp '/tmp'.

在实际文件夹中，有会话文件...所以我知道这不是文件写入问题.我还确保每个文件都是 utf-8 和 bom 以确保一致性.

In the actual folder, there are session files... so i know it is not a file writing issue. I have also ensured that every file is utf-8 with bom to ensure consistency.

如果您还有其他的解决方案，请帮我解决.它让我发疯.

If there are any other solutions you can think of, please help me solve this. It is driving me insane.

谢谢！！！

推荐答案

对于您的情况，我能想到的 3 种可能性是:

The 3 possibilities I can think of for your situation are:

1. 你如何调用 session_id()?在您的问题中包含该代码.如果您使用 any 参数调用它，它会将会话 ID 覆盖为您传递的任何参数.
2. 您的浏览器是否启用了 Cookie?会话 ID 作为 cookie 发送到浏览器.
3. 您是否随时调用 session_destroy() ?这将从服务器中删除会话数据，并导致在后续网页浏览时启动新会话.

1. How are you calling session_id()? Include that code in your question. If you're calling it with any arguments it will override the session ID to whatever argument you passed.
2. Are cookies enabled in your browser? The session ID is sent to the browser as a cookie.
3. Are you calling session_destroy() at any point? This will delete the session data from the server and cause a new session to be started on subsequent pageviews.
