title: Single URL for all Sub URL in PHP & HTML
body: <p>I need that if the user is at <code>www.xyz.com/z</code> or say <code>www.xyz.com/z.trial.php</code> or say <code>www.xyz.com/offer.php</code> for all this the URL bar should show only and only <strong>www.xyz.com</strong>.</p>
  
  <p>Yes, it's easy to have <strong>iframe</strong>, but <code>iframe</code> does not work for the URL copied and pasted manually in <strong>URL</strong> bar.</p>
  
  <p>I will be thankful if someone provides me the hint for the code.</p>
