PHP：会话在标题重定向之前未保存 [英] PHP: session isn't saving before header redirect

问题描述

我已经阅读了这个问题的PHP手册，这似乎是一个很常见的问题，但我还没有找到解决方案。我将会话保存在数据库中。
我的代码如下：

  // session 
 $ _SESSION ['userID'] = $用户>编号; 
 header（'Location：/subdirectory/index.php'）; 
  

然后在 session_start（）之后的index.php顶部， code>，我var_dumped $ _SESSION全局和用户ID不在那里。正如我所说的，通过PHP手册（ http://php.net/manual/en/function.session-write-close.php ）查看并且 session_write_close 或 session_regenerate_id（true）为我工作。
有人知道解决方案吗？



编辑：我在我的文件顶部有session_start（）。当我在页面重定向之前var_dump会话全局时，我看到了那里的用户标识，但没有在其他文件中，这是在这个脚本的子目录中

解决方案

我知道这是一个旧的toppic，但我找到了解决方案（对我来说）。
我在标题后面放了一个退出。

  $ _ SESSION ['session'] ='这是一个会议; 
 header（'location：apage.php'）; 
出口; 
  

这适用于我

I have read through the php manual for this problem and it seems quite a common issue but i have yet to find a solution. I am saving sessions in a database. My code is as follows:

// session
$_SESSION['userID'] = $user->id;        
header('Location: /subdirectory/index.php');

Then at the top of index.php after the session_start(), i have var_dumped the $_SESSION global and the userID is not in there. As i said ive looked through the PHP manual (http://php.net/manual/en/function.session-write-close.php) and neither session_write_close or session_regenerate_id(true) worked for me. Does anybody know a solution?

Edit: I have session_start() at the top of my file. When i var_dump the session global before the header redirect, i see the userID in there, but not in the other file, which is in a subdirectory of this script

解决方案

I know this is an old toppic but I found the solution (for me). I've put a exit after the header.

$_SESSION['session'] = 'this is a session';
header('location: apage.php');
exit;

This works for me
