If a session is already open, PHP generally just uses that session
and does not try to open another one.

>The need is to force only one user at the same time.

Since there are plenty of ways to leave a session without informing
PHP of that, this is going to be a severe problem. You can time
out sessions but that can be very annoying to your users. Indefinite
lockouts are even worse.

>I'm currently using the database but also looking at a php only solution.

There really isn't a good solution, period, unless allowing a user
a maximum of zero sessions is acceptable.
