title: Can't reference parent directory in symfony with require_once?
body: <p>I'm using symfony and trying to reference a file that's in a parent directory like so:</p>
  
  <p><code>require_once('../MyClass.class.php');</code></p>
  
  <p>It doesn't seem to be working though it keeps saying it can't find the file when I run the task. I tried the same code on my personal WAMP server (as opposed to going through this server) and that doesn't use symfony and it worked fine.</p>
  
  <p>I'm not sure why symfony can't find it?</p>
  
  <p>Thanks</p>
