title: Fatal error: require_once() [function.require]: Failed opening required
body: <p>I am working in php project, its giving the error as:</p>
  
  <pre><code>Warning:
  </code></pre>
  
  <blockquote>
    <p>require_once(ROOT_PATH/lib/confs/Conf.php) [function.require-once]: failed to open stream: No such file or directory in ..\htdocs\GProject\lib\exception\ExceptionHandler.php on line 20</p>
    
    <p>Fatal error: require_once() [function.require]: Failed opening required 'ROOT_PATH/lib/confs/Conf.php' (include_path='.;C:\php5\pear') in ..\htdocs\GProject\lib\exception\ExceptionHandler.php on line 20</p>
  </blockquote>
  
  <p>But in <code>\ExceptionHandler.php</code> file, the 20th line is</p>
  
  <pre><code>require_once ROOT_PATH . '/lib/confs/Conf.php';
  </code></pre>
  
  <p>And I have the file Conf.php under the <code>lib/confs/Conf.php</code> itself, even though I am getting the error.</p>
  
  <p>What may be the problem.
  Thanks in advance.</p>
