amalosoul Posted August 15, 2006 Share Posted August 15, 2006 Can I find out specific information about an user who opens a php page (like ip address). I need to create a program which doesn't allow multiple registrations from the same computer. I know that $_SERVER stores this kind of information, but I don't know which argument to use.

wildteen88 Posted August 15, 2006 Share Posted August 15, 2006 Use $_SERVER['REMOTE_ADDR'] however keep in mind this variable may not return the users true IP address as it may return the users proxy address if they are behind a proxy. Also most ISPs give customers dynamic IP addresses, which mean their IP address could change automatically when they connect to the internet, connect to a website, change every minutes/hours etc. So using $_SERVER['REMOTE_ADDR'] shouldn't be relied on.
