This is – geoplugin.class.php

1st Way:

<?php
require_once('php/geoplugin.class.php');
$geoplugin = new geoPlugin();
$geoplugin->locate();
// create a variable for the country code
$countryCode = $geoplugin->countryCode;

switch($countryCode) {
    case AU:
       header('Location: http://au.state.com/');
        break;
    case US:
       header('Location: http://us.state.com/');
        break;
    case IN:
       header('Location: http://in.state.com/');
        break;
}
?>

Or

<?php
require_once('php/geoplugin.class.php');
$geoplugin = new geoPlugin();
$geoplugin->locate();
// create a variable for the country code
$countryCode = $geoplugin->countryCode;
// redirect based on country code:
if ($countryCode == "AU") {
    header('Location: http://au.state.com/');
}
else if ($countryCode == "IN") {
    header('Location: http://in.state.com/');
}
else if ($countryCode == "BD") {
    header('Location: http://bd.state.com/');
}
else if ($countryCode == "US") {
    header('Location: http://us.state.com/');
}
else {
    header('Location: http://state.com/');
}
?>
