[php] PHP sessions default timeout

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?

Yes, that's usually happens after 1440s (24 minutes)

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
