title: PHP __DIR__ or __FILE__ symlinked
body: <p>Using <code>__DIR__</code> and <code>__FILE__</code> constants do not work in a symlinked situation.  What is the workaround for this?</p>
  
  <p>For example:</p>
  
  <p>I have a file:</p>
  
  <pre><code>/home/me/modules/myfile.php
  </code></pre>
  
  <p>It is symlinked to:</p>
  
  <pre><code>/var/www/project/app/myfile.php
  </code></pre>
  
  <p>from in <code>/home/me/modules/myfile.php</code> i need to include a file that is located in <code>/var/www/project</code></p>
  
  <p>EDIT</p>
  
  <p>To the suggestions of using realpath() - unfortunately this does not work.</p>
  
  <pre><code>var_dump(__DIR__);
  var_dump(realpath(__DIR__));
  </code></pre>
  
  <p>both return exactly the same filepath</p>
