Re: Best way to get the remote IP address?

That's because it's probably not so much a PHP thing. X-Forwarded-For is normally used when going through a proxy. Say my internal IP is 192.168.1.15, and my proxy's official IP address is 132.248.10.2, then we'd have this: REMOTE_ADDR=132.248.10.2 X_FORWARDED_FOR=192.168.1.15 That way, even when going through a proxy, there's information about who originally submitted the request.
