title: do I need HTMLpurifier in Codeigniter?
body: <p>I am developing a PHP application using Codeigniter framework and it is time now for the security reviews.. I got many recommendations to use <a href="http://htmlpurifier.org" rel="nofollow noreferrer">HTMLPurifier</a> library if i want the best protection I can get.. is this true? do I really need this library or are there better options? I appreciate your thoughts on this issue</p>
