I have read some discussion about HTTP_X_FORWARDED_FOR before, so after a little browsing i found this on the php.net website
PHP Code:
if ($_SERVER["HTTP_X_FORWARDED_FOR"]) {
if ($_SERVER["HTTP_CLIENT_IP"]) {
$proxy = $_SERVER["HTTP_CLIENT_IP"];
} else {
$proxy = $_SERVER["REMOTE_ADDR"];
}
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
} else {
if ($_SERVER["HTTP_CLIENT_IP"]) {
$ip = $_SERVER["HTTP_CLIENT_IP"];
} else {
$ip = $_SERVER["REMOTE_ADDR"];
}
}
Seems like that will give a more accurate IP (granted not a definite one)
Edit: By the looks of things HTTP_X_FORWARDED_FOR can contain a comma delimited list (when a user has been through multiple proxies) so it might be worth exploding that aswell. |
