get list of all PHP session_id

Question

Is't possible to get list of all session_id in PHP SESSIONS?

Note: I need maintained some file in the server. One file equal one session. And I need to determine behaviour of old files if SESSION expire.

Thank you all for any advice.

As others have answered, sessions are stored in the path defined by session.save_path in php.ini and you can iterate this directory to retrieve a list of every session.

An alternative approach would be to change the session storage and move it to a database using session_set_save_handler(). You could store all your sessions in a database and do with it whatever you wish.
