title: PHP Simple HTML DOM parser - print class name
body: <p>I have little problem with parsing some data from one webpage. 
  I'm trying to get class name of certain <code>div</code>.</p>
  
  <p>Example: </p>
  
  <pre><code>&lt; div class="stars b3"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I want to save in array just <code>b3</code>. 
  Is it possible to do this?</p>
  
  <p>Thanks!</p>
