When/How PHP session expire? Can I set it in minutes of inactivity?

[Ryan Hubbard]

I would like to limit multiple logins for a user. How and when does
the session id expire? Can I set it so after x minutes of inactivity
it would expire. How do I check if session id exists? If I can do
these two things then I can store the session id for a user in a
database and everytime he requests an action I can just check if the
session id is active or expired. If active let him continue if
expired request to relogin. If the user tries to login and the
session id is active then reports that the id is still active and he
must either log out of the session or wait till it expires. How would
I accomplish this? Thanks

session_cache_expire();

How do I check if session id exists?

session_is_registered();

Is session_cache_expire the number of minutes from start to end or the
number of minutes from the last activity? Thanks for your help I
can't seem to find the answer in the PHP manual.

see session.gc_maxlifetime, session.cookie_lifetime in your php.ini.
If you are unable to edit it, see ini_set(); function

Are you really helping him??

To the OP:

Manual is your friend.
<http://in.php.net/manual/en/ref.session.php> Change your INI settings
to various values and learn.

Search the archive and Google for nice login scripts.
