There is session area in php.ini.
Usually sesion problem because of missing session save path

[Session]
; Handler used to store/retrieve data.
session.save_handler = files
 
; Argument passed to save_handler.  In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this 
; variable in order to use PHP's session functions.
; As of PHP 4.0.1, you can define the path as:
;     session.save_path = "N;/path"
; where N is an integer.  Instead of storing all the session files in 
; /path, what this will do is use subdirectories N-levels deep, and 
; store the session data in those directories.  This is useful if you 
; or your OS have problems with lots of files in one directory, and is 
; a more efficient layout for servers that handle lots of sessions.
; NOTE 1: PHP will not create this directory structure automatically.
;         You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
;         use subdirectories for session storage
 session.save_path = "\xampp\tmp"
;u can fill it with absolute path like "c:\Windows\Temp"
