Sometimes you want to grab the connecting web client's IP address in a PHP script. This is how:

if ( isset($_SERVER["REMOTE_ADDR"]) ) {
echo '' . $_SERVER["REMOTE_ADDR"] . ' ';
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) ) {
echo '' . $_SERVER["HTTP_X_FORWARDED_FOR"] . ' ';
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) ) {
echo '' . $_SERVER["HTTP_CLIENT_IP"] . ' ';
}
?>
