问题描述
我今天面对phpCas库。
I am facing a problem today with the phpCas library https://wiki.jasig.org/display/CASC/phpCAS.
问题如下，当我尝试使用某些注销功能时，收到消息
Problem is the following, when I try to use some logout function, I got the message
Warning: session_destroy(): Trying to destroy uninitialized session
快速浏览了phpCas的库代码后，我设法弄清了问题的根源，这是注销功能的代码段：
After giving a quick look into the phpCas's library code, I manage to figure out where the problem comes from, here is a snippet of a logout function :
session_write_close();
header('Location: '.$cas_url);
phpCAS::trace("Prepare redirect to : ".$cas_url);
session_unset();
session_destroy();
那里的问题似乎是 session_write_close（）实际上关闭了会话，然后 session_destroy（）无法工作。
The problem there it seems is that session_write_close() actually close the session then session_destroy() can't work.
试图在 session_write_close（）中添加注释，并且看起来很吸引人，但它引出了两个问题：
Tried to put the session_write_close() in comment and worked like a charm but it leads to two questions :
-
问题真的来自那里吗？还是应该起作用？
Is the problem really coming from there? Or should it work?
如果问题确实出在那儿，为什么会出现在那儿而没人抱怨呢？认为phpCas是许多人使用的知名库。
If the problem do really come from there, why is it there and nobody complaining? Thought phpCas was a reknown library used by many.
推荐答案
像您一样的声音检出了master分支（2af859ff76）-刚刚检查过，但确实有错误。您应该：
Sounds like you checked out the master branch (2af859ff76) - just checked and it does have an error in it. You should:
- 签出一个发行分支，如1.3稳定
- 登录此作者的错误
