expiring sessions

P: n/a
I've seen a couple of questions regarding the
expiring of sessions in PHP. The way to control
how sessions expire is to set some options
in php.ini.

These options are of particular use:
session.gc_probability
session.gc_maxlifetime
session.cache_expire

session.gc_probability is a percentage. 1 means 1%,
and 100 means 100%. If you want to ensure
that the gc (garbage collector) is run on every
activation of the session subsystem, set
gc_probability to 100:

session.gc_probability = 100

Of course, this will probably have performance
consequences. Followups to comp.lang.php.
