PHP sessions default timeout

Question

Do PHP sessions timeout by default - ie without any coding on my part would a user eventually be "logged out" after some time of inactivity?

Thanks for all those. I wanted a little more straight forward answer hence the question! - upvoted — KB., Mar 28 '12 at 09:06
Amusing how all the answers mention "20 minutes" and "1440 seconds" and no one bothered to notice that 1440 seconds is in fact 24 minutes. — maligree, Jul 09 '12 at 08:55

It depends on the server configuration or the relevant directives session.gc_maxlifetime in php.ini.

Typically the default is 24 minutes (1440 seconds), but your webhost may have altered the default to something else.

You can change it in you php-configuration on your webserver. Search in php.ini for

session.gc_maxlifetime() The value is set in Seconds.

You can set the session time out in php.ini. The default value is 1440 seconds

session.gc_maxlifetime = 1440

; NOTE: If you are using the subdirectory option for storing session files
;       (see session.save_path above), then garbage collection does *not*
;       happen automatically.  You will need to do your own garbage
;       collection through a shell script, cron entry, or some other method.
;       For example, the following script would is the equivalent of
;       setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):
;          find /path/to/sessions -cmin +24 -type f | xargs rm
