Calculate A/B/N Testing significance in PHP and create mailing from it

I have a mysql table containing version, views and sales. I need significance be calculated for A/B/N Testings, so for MORE than only 2 versions. So it could be A/B/C/D, etc. So preferably I would like to have one function, that returns significance and the probability. And second I would prefer to have another function to create a nicely looking table colored in green for the winning version, either in html or ASCII style, that I can send in an email.
