title: dir manipulation(__DIR__) not working
body: <p>the following behaves different in <strong>host</strong>:</p>
  
  <pre><code>echo 'DIR:' .__DIR__; // DIR:__DIR__
  </code></pre>
  
  <p><strong>localhost:</strong>(works fine):</p>
  
  <pre><code>DIR:C:\Program Files\VertrigoServ\www
  </code></pre>
  
  <p>why this different output?</p>
