How to Automatically Redirect Users to Specific Subdomains Based on Their IP Address and Country?

Redirecting Domains Based on User IP Address by Country

This guide addresses the issue of automatically redirecting users to specified subdomains based on their IP address to cater to different geographical regions.

To achieve this, a widely used method involves utilizing the geoPlugin class. The class can be downloaded from http://www.geoplugin.com/_media/webservices/geoplugin.class.phps.

Redirection Implementation

Create an index.php file in your root folder and include the following code:

<code class="php"><?php
require_once('geoplugin.class.php');
$geoplugin = new geoPlugin();
$geoplugin->locate();

// Country code variable
$var_country_code = $geoplugin->countryCode;

// Redirection based on country code
if ($var_country_code == "AL") {
    header('Location: http://sq.wikipedia.org/');
} elseif ($var_country_code == "NL") {
    header('Location: http://nl.wikipedia.org/');
} else {
    header('Location: http://en.wikipedia.org/');
}
?></code>

The script locates the user's IP address and retrieves the corresponding country code. Based on the code, the user is redirected to the appropriate subdomain.
