$ _SESSION问题 - 页面重新加载会创建新的会话ID [英] $_SESSION problem - page reload creates new Session ID
问题描述
您好，
我在使用会话变量时遇到问题
PHP 4.3.9
操作系统：Win XP教授
Web服务器IIS（本地并且没有其他服务器的链接来自我工作的网页
）
浏览器：IE 6.0
我遇到的问题是，每次重新加载相同的PHP页面时，我都会得到
a不同
会话ID （因此所有会话变量都会从一个页面丢失到另一个页面。）
让我们说在firstpage.php我设置
$ _SESSION [" ; firstvar"] =" someval";
$ _SESSION [" secvar"] =" otherval";
和secpage.php I尝试检索$ _SESSION [" firstvar"]，它给了我
" Undefined Index error"
我不知道发生了什么，打印出会话时id（echo
SID;）我发现
每次重新加载页面或移动到
另一页。
问题是我不知道什么会重置会话，因为我使用
" session_auto_start" ;
并没有使用session_start，session_destroy或其他任何东西。
有人能给我一个暗示可能导致这种情况的原因吗？
谢谢

Hello,
I am having trouble using the session vars in
PHP 4.3.9
OS: Win XP Prof
Web Server IIS (is local and there are no links to other servers from
the web pages I work on)
Browser: IE 6.0
The problem I am having is that each time I reload the same PHP page, I get
a different
Session ID (and thus all session vars are lost from one page to another).
let''s say in firstpage.php I set
$_SESSION["firstvar"] = "someval";
$_SESSION["secvar"] = "otherval";
and in secpage.php I try to retrieve $_SESSION["firstvar"] , it gives me
"Undefined Index error"
I did not know what is happening and when printing out the session id (echo
SID;) I found out
that the ID is changing every time page is reloaded or when moving to
another page.
The problem is that I don''t know what might reset the session since I use
"session_auto_start"
and have not played with session_start, session_destroy or anything else.
Can someone give me a hint on what might cause this ?
Thanks
