title: Which file has called one other?
body: <p>Is there any way to determine the file which has called one other. E.g. </p>
  
  <h3>FILE <code>one.php</code>:</h3>
  
  <pre><code>include('two.php');
  ...
  </code></pre>
  
  <h3>FILE <code>two.php</code>:</h3>
  
  <p>// This file do some stuff</p>
  
  <p>I'm getting a 500 internal server error on <code>two.php</code> (<em>unexpected end of file in two.php</em>).</p>
  
  <p>However, the file has not an unexpected EOF, so I'm guessing that the issue comes from the file <code>one.php</code>. The problem is that I don't know which is that file. Any ideas?</p>
