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

[SYP}{ER]

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

getenv ("REMOTE_ADDR");

or

$_SERVER["REMOTE_ADDR"];

PHP Code:

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 )
