Getting users IP

[Anon]

Hi,

How do i find out the IP address of the user visiting my site? I want to be able to check for the same IP's returning to the site and present a personal greeting.

Thanks,
Charkus

<?php

$ip = $REMOTE_ADDR;
print("Welcome $ip!");

?>

[[deleted]]

$HTTP_SERVER_VARS['REMOTE_ADDR']

to be exact...

and from 4.1.x+ it will be

$_SERVER['REMOTE_ADDR']

Many ip addresses are assigned dynamically. So a return visitor might have a different one, and the same one might be someone else.
