title: Loading PHP file into DIV via AJAX
body: <p>Say I have an <code>index.php</code> that loads a <code>page.php</code> into the <code>div</code> of class '<code>wrapper</code>'.</p>
  
  <p><code>page.php</code> in turn has its own links and I want it so that when you click on one of these links it loads the respective page into the SAME '<code>wrapper</code>' <code>div</code>. </p>
  
  <p>Similarly that loaded page might have its own links and I want to continue loading content into the same div. How might I achieve this chain effect of pages?</p>
