win下安装wdb的问题

[wjq]

最近换了一个服务商,把linux服务器换成win2003的全能主机,发现wdb出问题,而且连全新安装也不行,主要问题就是session问题,如果有temp文件夹就会出现500错误,如果没有temp文件夹就会出现:
Warning: session_start() [function.session-start]: open(temp\sess_340129576e479d754f4b4ca6c6d9f292, O_RDWR) failed: No such file or directory (2) in D:\wwwroot\52ecust123\wwwroot\new\global.php on line 30

大家看看如何解决问题.

tmp
非temp

Cannot modify header information
表示页面有输出
八成是session连锁反应出来的

[johnpanq]

temp文件夹一定要有，不然session无法写入，
而且temp文件夹的权限要允许写入

[szjq]

可以在windows服务器的php.ini文件中把session的保存路径改成别的目录，/tmp目录windows下没有，所以出错了
