Hi,

how to detect if a user closes the browser and so ends the php session?
(i have a login system and i need to know if somebody doesn't logout of
it, just closes the browser).

For example: i have user1 with a username and password, i just want to
disable somebody to double login with the same username and password (at
the same time of course).

What is the best way to do it?

tnx,
Greg
