[session 删除]请教如何删除过期的session文件？

已经定义了session存放的路径，
如何删除过期session产生的文件？或者用户关闭浏览器时就自动删除session产生的文件？

session.gc_maxlifetime integer
session.gc_maxlifetime specifies the number of seconds after which data will be seen as 'garbage' and cleaned up.

注: If you are using the default file-based session handler, your filesystem must keep track of access times (atime). Windows FAT does not so you will have to come up with another way to handle garbage collecting your session if you are stuck with a FAT filesystem or any other fs where atime tracking is not available. Since PHP 4.2.3 it has used mtime (modified date) instead of atime. So, you won't have problems with filesystems where atime tracking is not available.
