title: Using RecursiveIteratorIterator with namespaces?
body: <p>My problem is that when I'm using namespaces, I can't use the RecursiveIteratorIterator Class of the Standard PHP Library.
  The following code :</p>
  
  <pre><code>&lt;?php namespace mynamespace;
  
      $arr = Array("abc", Array("def", "ghi", Array("jkl")));
      $it = new RecursiveIteratorIterator(new RecursiveArrayIterator($arr));
      $result = iterator_to_array($it, false);
  
  ?&gt;
  </code></pre>
  
  <p>Returns:</p>
  
  <blockquote>
    <p>PHP Fatal error:  Uncaught Error: Class 'mynamespace\RecursiveIteratorIterator' not found in ...</p>
  </blockquote>
