Previously, the Zend_Filter module of the Zend Framework was reviewed on SitePoint. Today, one of the contributors to the framework, Chris Shiflett, has some of his responses to the comments made.

Maarten Manders graciously took the time to review the Zend_Filter component of the Zend Framework. I think criticism and public discussion are healthy. Unfortunately, I don't have time to offer a very detailed response, but I'll try to remedy that with a followup post later in the week.

One thing worth noting is that Zend_Filter was extracted from Zend_InputFilter shortly before the preview release. Because it provides such a rigid approach to input filtering, some contributors pointed out that Zend_InputFilter does not provide enough flexibility for simple cases such as filtering an argument passed to a method.

Chris also goes on to comment that the Zend_Filter class is, in his opinion, "far from impressive". Of course, paired with its (older) brother, Zend_InputFilter, it can lead to some much better results. The wraps up the post with a brief, high-level introduction to the Zend_InputFilter class just so everyone's on the same page.
