title: Using Zend_filter_input standalone
body: <p>Is it possible to use Zend_Filter_Input as a generic input filter? I want to use it to filter all form fields (strip tags etc but no validation). All the examples seem to include a $validators array and pre-suppose that I will know the names of the fields on the way in.</p>
  
  <p>Because of the nature of the project, timescales etc, it is not possible to rewrite the forms using Zend_Form. There is a generic Form class which handles all form input so I need to do the filtering in there.</p>
  
  <p>Thanks!</p>
