PHP会话变量在页面之间变化

Question

我有一个我设置的会话变量:

<?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:

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

问题是它们不匹配.我得到两个完全不同的字符串.register_globals已关闭.我注意到当我设置md5(....)为常量字符串时,例如:md5('example')它按预期工作,两个字符串匹配.但那应该不重要.关于这里发生了什么的任何想法？

我不太清楚如何阅读它,但它在我看来我的文件(我假设的index.php是'/')被调用了三次.我读得对吗？那里发生了什么？

我的错误完全是愚蠢的。我<img>那里有一些空标签导致了额外的请求。捂脸抱歉大家，问题解决了。感谢您的帮助！！
