title: In php, require in required file?
body: <p>In php, if i have a file that requires a file from a subdirectory like:</p>
  
  <pre><code>require('directory/file.php');
  </code></pre>
  
  <p>and <code>file.php</code> wants to require another file in its own directory, is the path relative to <code>file.php</code> or the file that it is included in?</p>
