Getting someones IP address

[kjc]

Does anyone know how I can get a visitors IP address. I am writing a discussion database and want to be able to log posters ip details.
Is this a PHP thing?

Thanks

This is the php:

<? $REMOTE_ADDR; ?>

in order to log it you'd need to do something like stick it in a MySQL databse.

Another question, How would I get someones username of a site visitor, using PHP -

eg someone.aol.com? :thumbsup:

Dunno if that's what you mean

gethostbyaddr($REMOTE_ADDR)

[mordred]

Username? If they registered with you, don't you have already their usernames?

getenv("HTTP_X_FORWARDED_FOR")

No that just gets the IP address.
I need the username that the user connects to the internet too.

like someone.freeserve.co.uk

Can only get a proxy address. Look at my reply again, I must've changed it as you was replying
