title: Zend Framework - adding a custom field to the session handler?
body: <p>hey all I'm using the Zend_Session_SaveHandler_DbTable Session handler and I was curious if anyone knows how to best add a custom field to the table that it stores the session data in? for example I'd like to be able to log the username of the person in the sessions table. </p>
  
  <p>Anyone know if that's possible with the Zend_Session_SaveHandler_DbTable? </p>
  
  <p>here's my set up code now..</p>
  
  <pre><code>$config = array(
    'name'           =&gt; 'session',
    'primary'        =&gt; 'id',
    'modifiedColumn' =&gt; 'modified',
    'dataColumn'     =&gt; 'data',
    'lifetimeColumn' =&gt; 'lifetime'
  </code></pre>
  
  <p>);
    Zend_Session::setSaveHandler(new Zend_Session_SaveHandler_DbTable($config));
    Zend_Session::start();</p>
