An Introduction To PHP Sessions

By Kevin Waterson, 22 May 2005 PHP Sessions Download PDF (2 comments)

When Do Sessions Expire?

The default behaviour for sessions is to keep a session open indefinitely and only to expire a session when the browser is closed. This behaviour can be changed in the php.ini file by altering the line:

Listing 22 Keeping a session alive indefinitely (listing-22.txt) 
session.cookie_lifetime = 0

If you wanted the session to finish in 5 minutes you would set this to:

Listing 23 Keeping a session alive for five minutes (listing-23.txt) 
session.cookie_lifetime = 300

Remember to restart your web server after making this change.
