How do I get the user's IP?

^^^as titled :thumbsup:

this should be the easiest way of doing that ...

<? echo $HTTP_SERVER_VARS["REMOTE_ADDR"] ?>

HormonX

$REMOTE_ADDR

is quite easy too, cheers anyhoo :thumbsup::D

Can you get the IP address of a computer behind a proxy server?

Not sure about the proxy thing, but a few other ways to get the IP

getenv ("REMOTE_ADDR");

or

$_SERVER["REMOTE_ADDR"];

:)

function getip() {
if (isSet($_SERVER)) {
if (isSet($_SERVER["HTTP_X_FORWARDED_FOR"])) {
$realip = $_SERVER["HTTP_X_FORWARDED_FOR"];
} elseif (isSet($_SERVER["HTTP_CLIENT_IP"])) {
$realip = $_SERVER["HTTP_CLIENT_IP"];
} else {
$realip = $_SERVER["REMOTE_ADDR"];
}

} else {
if ( getenv( 'HTTP_X_FORWARDED_FOR' ) ) {
$realip = getenv( 'HTTP_X_FORWARDED_FOR' );
} elseif ( getenv( 'HTTP_CLIENT_IP' ) ) {
$realip = getenv( 'HTTP_CLIENT_IP' );
} else {
$realip = getenv( 'REMOTE_ADDR' );
}
}
return $realip;
}

You might need to amend the $_SERVER calls to $HTTP_SERVER_VARS (note: I'm pretty sure I copied that from php.net somepage so don't blame me if it works properly ;))
