# session_save_path

(PHP 4, PHP 5)

session_save_path -- Get and/or set the current session save path

## Description

string session_save_path ( [string path] )

session_save_path() returns the path of the current directory used to save session data. If path is specified, the path to which data is saved will be changed. session_save_path() needs to be called before session_start() for that purpose.

> 注: On some operating systems, you may want to specify a path on a filesystem that handles lots of small files efficiently. For example, on Linux, reiserfs may provide better performance than ext2fs.

See also the session.save_path configuration directive.
