页面之间的PHP会话变量更改 [英] PHP session variable changes between pages

问题描述

我有一个这样设置的会话变量:

I have a session variable that I set like this:

<?php
$token = md5(uniqid(rand(), true));
session_start();
$_SESSION['token'] = $token;
print $_SESSION['token'];
?>

然后在另一页上，我有这个:

Then on another page I have this:

<?php
session_start();
print $_SESSION['token'];
?>

问题在于它们不匹配.我得到两个完全不同的字符串. register_globals已关闭.我确实注意到，当我将md5(....)设置为常量字符串时，例如:md5('example')，它可以按预期工作并且两个字符串匹配.但这没关系.对这里发生的事情有任何想法吗?

The problem is that they don't match. I get two completely different strings. register_globals is off. I did notice that when I set md5(....) to a constant string eg: md5('example') that it works as expected and the two strings match. But that shouldn't matter. Any ideas on what's going on here?

我不太确定该怎么读，但是在我看来我的文件(我认为是"/"的index.php)被调用了三次.我读对了吗?那里发生了什么事?

I'm not quite sure how to read that but it looks to me that my file (index.php which I assume is the '/') is being called three times. Am I reading that right? What's going on there?

推荐答案

完全是我的愚蠢错误.我那里有一些空的<img>标记，这些标记引起了额外的请求. facepalm 抱歉，问题解决了.谢谢您的帮助！

Completely stupid mistake on my part. I had some empty <img> tags in there that were causing the extra requests. facepalm Sorry everyone, problem solved. Thanks for your help!!
