As you may know PHP 5.2.0 will feature a very capable filtering extension that can be used to easily validate your input via a number of rules which you can find here. What I am interested in hearing is are there any other common types of data collected by PHP forms that would be worth while adding filters for into the extension. My own suggestions would be the phone (US/EU formats) and postal/zip code validators.

So let's hear what you have to say

Brief Disclaimer: Consider this an RFC of sorts, the suggestions if widely supported may not get integrated and any additions will need to have the implicit agreement of all the filter extension developers before being added.
