Re: [Phplib-users] One User logged in at the same time...

You have to approach it in a different manner. I implemented this and it
works very nicely to keep multiple users out of the one account :)

When someone logs in, set a cookie on their machine with a session
ID(SID) and record this session ID in a table along with their UID.
There's only one record in that table per user. Each time they visit the
site you check that table so that the UID matches the SID, if not, they
must be logged in twice!
What this does is effectively logout the first user. The second user
gets in and knocks the first off. When the first user logs in again the
SID is updated and the second user then gets logged out. This should
discourage people sharing their login info fairly quickly and gets over
the problem of trying to figure out when people logout!
