title: Can CodeIgniter Helper Functions use database functions?
body: <p>One of my CodeIgniter Controller functions needs to call a recursive function as part of its functionality.  The function call chokes if I put it inside the controller class, and it can't access database functions <code>($this-&gt;db-&gt;get())</code> if I put it outside the class.  Would making it a helper function fix this problem?</p>
