How to Achieve Subdomain Redirection Based on GeoIP Location?

GeoIP Redirection for Subdomains

In order to set up automatic redirection of users to corresponding subdomains based on their country's IP address, follow these steps:

1. Acquire the geoPlugin Class:
   Download geoPlugin from http://www.geoplugin.com/_media/webservices/geoplugin.class.php. This library provides a free limit of 120 requests per minute, and blocks access for an hour if the limit is exceeded. The block will automatically lift after an hour.
2. Create an index.php File:
   Place an index.php file in your website's root folder. It should contain the following code:

<code class="php"><?php
require_once('geoplugin.class.php');
$geoplugin = new geoPlugin();
$geoplugin->locate();
$var_country_code = $geoplugin->countryCode;
if ($var_country_code == "AL") {
  header('Location: http://sq.wikipedia.org/');
}
else if ($var_country_code == "NL") {
  header('Location: http://nl.wikipedia.org/');
}
else {
  header('Location: http://en.wikipedia.org/');
}
?></code>

3. Customize Redirection Logic:
   In the provided code, the redirection is based on the country code. You can replace the Wikipedia URLs with your desired subdomains. Refer to http://www.geoplugin.com/iso3166 for a list of country codes.
