package for detecting users contry in php?
I have a site, kind of like a dating site where users sign up and list their location, so london or birmingham etc. I want to be able to capture a guests IP and if they are based in london have all the users in london show up as local in their area.
Is this possible? I havn't got the first clue about how this could be done, it's really just to ask and see if it is possible and to see if someone could push me in the right direction please.
Thanks
