title: Opencart module include custom php file issue?
body: <p>I'm trying to create an OpenCart 1.5.1.3 module. The issue I'm having is with including a custom php script.</p>
  
  <p>When I do this in the controller:</p>
  
  <pre><code>include('module/simple_html_dom.php');
  </code></pre>
  
  <p>or</p>
  
  <pre><code>include('simple_html_dom.php');
  </code></pre>
  
  <p>I'm presented with the following error:</p>
  
  <blockquote>
    <p><strong>Notice</strong>: Error: Could not load language module/simple_html_dom! in <strong>D:\xampp\htdocs\store\system\library\language.php</strong> on line <strong>26</strong></p>
  </blockquote>
  
  <p>I suspect there's a simple explanation, but just can't work it out.</p>
