title: php nested include behavior
body: <p>In many places in my code, I do things like:</p>
  
  <pre><code>file1.php:
  &lt;?php
  include('../file2.php');
  
  file2.php:
  &lt;?php
  include('anotherdirectory/file3.php');
  </code></pre>
  
  <p>Depending on the server or settings I try this on, it either sets the relative paths from the "includer" or from the "includee". This is really confusing.
  So file1 might try to include "../anotherdirectory/file3.php" or it might try "anotherdirectory/file3.php".</p>
  
  <p>What settings dictate this behavior? I want to have control over this...</p>
