用了一段时间HEX发布的SESSION类，发现如下错误

sking

用了一段HEX发布的替代CI自己SESSION的类，将应用放上服务器后时不时报如下错误：

A PHP Error was encountered

以上错误时同时报在一个页面上的，望HEX兄指教错在什么地方，谢谢!

Hex

很简单，这个
C:/DOCUME~1/ADMINI~1/LOCALS~1/Temp/1\sess_70a13c1adc9b4ad1c7eea6bc32b3b061 文件不存在，原因我想是 temp 目录不存在或者没权限。
这个是 PHP 本身的配置问题，你必须为 PHP Session 配置一个存放的地方，这个在 php.ini 中配置，和 CI 无关。

明白了，多谢HEX！
