My session variables are resetting every time I load a new page.

I have included a header.php file to each script with the session_start() function at the very top like so:

session_start();
error_reporting(E_ERROR);

I have also checked to make sure that the session_id is the same across all pages and it is.

I checked my web host's php_ini config file and I saw that the session.save_path was set to /tmp. I changed it to /var/lib/session/ like someone had suggested on this site and I began to get odd warnings in my code.

Warning: session_start() [function.session-start]: open(/var/lib/php/session//sess_97fca6d21c7ffa8333cd42eaa87f2eac, O_RDWR) failed: Permission denied (13) in /home/mforsyth/public_html/Beesting/header.php on line 2

I do not know what to do to fix this problem. Any help would be useful. If more details are needed please let me know.

EDIT: I have changed the folder back to /tmp and have made sure i can read/write into it and I can. I have also echoed the session id on every page and it all comes out the same. Also it seems that the session only lasts for one page

发生的事情是 php 尝试使用它写入 ThinkingMonkey 提到的目录的一些信息来跟踪您的会话。

由于 php/webserver 进程的用户无法写入该目录，因此失败。因此，您没有获得会话。

找出进程在哪个用户下运行，并授予他对该目录的读/写权限。

谢谢您的帮助。在进一步调查并与我的主人讨论此事后，我能够得出结论，问题不在于写入 /tmp 文件夹的能力。实际上问题出在我的 header.php 包含文件中的一个 javascript 函数。

function logout()
{
    <?
session_destroy();
?>
alert("you have been logged out");
}

它避免了它在函数中的事实，这可能是我看到两种语言的编译方式不同的错。我做了一个简单的 ajax 调用来处理会话销毁，现在一切都很好。我想知道那里是否还有其他人有类似的问题，这是否对他们有帮助。

尝试重启webserver和php服务，如果是nginx/php-fpm，试试

root@server > service nginx restart
root@server > service php-fpm restart

这应该够了吧！

有同样的一般问题，结果出于某种原因我使用 JavaScript 来删除会话 cookie。

document.cookie = '[session_name]' +'=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;';
