title: How do I Instantiate a class within a class in .php
body: <p>I'm new to OOP and I can't figure out why this isn't working.  Is it not ok to instantiate a class with in a class.  I've tried this with included file with in the method and it didn't make a change.</p>
  
  <pre><code>include('Activate.php');
  
  class First {
      function __construct() {
      $this-&gt;activate();
      }       
      private function activate() {
      $go = new Activate('Approved');
      }
  }
  
  $run = new First();
  </code></pre>
