session_save_path — Get and/or set the current session save path
session_save_path ([ string|null $path = null ] ) : string|false
session_save_path() returns the path of the current directory used to save session data.
Session data path. If specified and not
null, the path to which data is saved will be changed. session_save_path() needs to be called before session_start() for that purpose.
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.
Returns the path of the current directory used for data storage, or
false on failure.
