确定PHP所读取的php.ini文件是你修改的那个php.ini文件?

[mynamesucks]

tmp目录存在吗

[li_li_feng_]

去哪里看？？？
我的C:\php 里没有

[anytimer]

(/tmp这个是linux下的,如果是windows系统请手动改一下php.ini文件的session.save_path = "c:\php"之类的可用路径

我在php.ini文件这样设置session.save_path = "c:\php"
并从起服务器，还是出现如下错误：

session的前面有输出，你可以自己搜索一下，这样的问题很多

[li_li_feng_]

那提示应该是说没有那个路径吧，我修改了路径为：
session.save_path = C:\php\session
确定有此路径，并从控制台重起了服务器，但是phpinfo();显示出的session.save_path /tmp /tmp
为什么还是这样？？？
必须从起机器吗？
用的是公司服务器，不能从起啊，怎么办那？？？

[ffphp]

在使用session的使用一要先开启session
session_start() //开启session
你开启了么

(加分)

已解决,不从起机器php就不重新读取ini文件,重起一下就好了
