Ilia Alshanetsky is asking the crowd for comments in his latest blog entry, specificalyl about the new filter extension coming in the next major PHP 5 series release - version 5.2.

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.

Comments on have already been made ranging from date validation improvements to input validation. Head on over and add your own comments/ideas to the mix...
