Try this code:
if(getenv("HTTP_X_FORWARDED_FOR"))
{
$ip=getenv("HTTP_X_FORWARDED_FOR");
}
else
{
$ip=getenv("REMOTE_ADDR");
}
$host = gethostbyaddr($ip);
And check out http://www.php.net/manual/en/function.getenv.php
However, I think it is very unsafe to base your payment transactions on these
features. If a criminal can get credit card data, he can sure get IP
addresses also.
