你可以在会话中切换PHP会话吗？ [英] Can You Switch PHP Sessions In a Session?

问题描述

我有两个应用程式，我想要统一。一个是我写的，另一个是我使用的CMS。我的身份验证发生在我编码的身份，我想让CMS知道这些信息。问题是CMS使用一个会话名称，我的应用程序使用另一个。我不想让它们使用相同的，因为可能的命名空间冲突，但我仍然想得到这个信息。

I have two apps that I'm trying to unify. One was written by me and another is a CMS I am using. My authentication happens in the one I coded and I'd like my CMS to know that information. The problem is that the CMS uses one session name, and my app uses another. I don't want to make them use the same one due to possible namespace conflicts but I'd still like to get this information.

是否可以切换会话名称在请求的中间？例如，在CMS中执行这样的操作：

Is it possible to switch session names in the middle of a request? For example, doing something like this in the CMS:

//session_start already called by cms by here

$oldSession = session_name();
session_name("SESSION_NAME_OF_MY_APP");
session_start();

//get values needed
session_name($oldSession);
session_start();

这样的工作吗？我在文档或网络上找不到任何东西，如果这样的话，在session_start（）被调用后会工作。提示？

Would something like this work? I can't find anything in the docs or on the web if something like this would work after session_start() has been called. Tips?

不管这个解决方案，我一直在考虑只是开发一个Web服务来获取信息，但显然只是从会话中获取它是更可取的，因为该信息已经可用。

Baring this solution, I've been considering just developing a Web Service to get the information, but obviously just getting it from the session would be preferable as that information is already available.

谢谢！

推荐答案

session_id('my1session');
session_start();
echo ini_get('session.name').'<br>';
echo '------------------------<br>';
$_SESSION['value'] = 'Hello world!';
echo session_id().'<br>';
echo $_SESSION['value'].'<br>';
session_write_close();
session_id('my2session');
session_start();
$_SESSION['value'] = 'Buy world!';
echo '------------------------<br>';
echo session_id().'<br>';
echo $_SESSION['value'].'<br>';
session_write_close();
session_id('my1session');
session_start();
echo '------------------------<br>';
echo $_SESSION['value'];

日志将如下所示：

PHPSESSID
------------------------
my1session
Hello world!
------------------------
my2session
Buy world!
------------------------
Hello world!

所以，你可以看到，会话变量保存和恢复，而改变会话。

So, as you can see, session variables saved and restored while changing session.
