PHP中的session不能跨页传递？一跨页就丢失，为空的！

本帖最后由 MoreQuestion 于 2011-03-20 07:57:23 编辑如先浏览a.php文件，里边写入一个会话值。

再浏览b.php，得到a.php写入的会话值。为空！

为什么呢？在本地机器上测试非常正常。一上传服务器就完了。

PHPINFO的session信息

session.save_path D:/hosting/user/html/temp D:/hosting/user/html/temp

这个文件夹可读可写。

当浏览a.php页时，产生一个有大小的文件，也保存了会话值。
当浏览b.php页时，产生一个大小为0的文件。拿不到？什么原因？

a.php

<?php<br />session_start();<br />?><br /><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><br /><html xmlns="http://www.w3.org/1999/xhtml"><br /><head><br /><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><br /><title>session set</title><br /></head><br /><br /><body><br /><?php<br />$_SESSION['session_value'] = 'value';<br />var_dump($_SESSION);<br />phpinfo();<br />?><br /></body><br /></html>

这个文件正常，可以打印出会话值。

b.php

<?php <br />session_start();<br>?><br>nbsp;html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><div class="clear">
