title: Loading the same PHP file from a subdomain with an indicator
body: <p>I have a top level domain where my main site is located.
  I want to create a subdomain for translation (e.g. "spanish.MyDomain.com ") so all the text would be in Spanish (I use a PHP translator for that purpose).</p>
  
  <p>How can I load my index.php file located in my main site's directory from the subdomain with a different version (i.e. a variable indicating the version should be in Spanish). 
  An alternative would be just to copy the index.php to the new "spanish" directory created on the server, but that would be a massive code duplication.</p>
  
  <p>Thanks,</p>
  
  <p>Joel</p>
