title: Decode ob_start() data
body: <p>This is definitely a newbie question, since I'm not sure where to start on this.</p>
  
  <p>I've used a PHP anti-spam form email script for years which was purchased from a developer (who has ceased their business) but is sometimes flagged as suspicious by our web host. It continues to work flawlessly, but I'd like to understand more what it's doing...</p>
  
  <p>Is there a way to decode what is wrapped into the following:</p>
  
  <pre><code>&lt;?php ob_start();?&gt;FJ3HbutclkZfpYfV4IA5oRr1gznnzEmBOY....?&gt;
  </code></pre>
  
  <p>The code, of course, is much longer than the above.</p>
  
  <p>Your ideas, suggestions are most appreciated.</p>
  
  <p>Dan</p>
