How to redirect users to sub sites based on their country IP location using CloudFlare API

The code snippet below is a demo in how to redirect users to subsites based on their country IP location.
On this code I am using CloudFlare geo location API – the code is not perfect but could be a good starting point 🙂

/**
 *
 * Collect the current state from the URL and CloudFlare
 */
$user_country_code = strtolower( $_SERVER[ "HTTP_CF_IPCOUNTRY" ] );
$site_subdomain = strtolower( array_shift( explode( ".",$_SERVER[ 'HTTP_HOST' ] ) ) );
if ( $user_country_code == $site_subdomain ) {
  // this is already using the country-code mapped version
  // do nothing
  } else {
    switch( $user_country_code ) {  // check if it's a country we currently support
       case 'et';
       case 'us';
       case 'gb'; 
       // yes - redirect to the specific subdomain
       header( 'Location: http://'.$user_country_code.'.example.com' );
       break;
       default;
       // no - redirect to www if not already there
       if ( 'www' == $site_subdomain ) {
         // already at www!
         // do nothing
       } else {
         // redirect to www
         header( 'Location: http://www.example.com' );
         break;
       }
    }     
}
