title: Zend Framework Session Namespace debugging print_r or equivalent
body: <p>Working with Zend, and the Sessions Namespace, trying to debug an issue I am running where I think something should be set, but it appears that it isn't so I'd like to find a means of seeing the whole namespace object but when I try <code>print_r()</code> or <code>var_dump()</code> on it, all I get is </p>
  
  <pre><code>Zend_Session_Namespace Object ( [_namespace:protected] =&gt; msp ) 
  </code></pre>
  
  <p>So I am wondering cause I can't find anything anywhere else on the subject currently is there a means of viewing that object? Is there a debug method that I can enable/disable for it through zend somehow?</p>
