Having recently written a Cold Fusion Markup Language version of a text captcha (a Section 508 compliant CAPTCHA, that is usable to individuals who are blind or deaf), it occurred to me that I could kill two birds and go ahead and write a PHP version too. My website’s commenting system has let a few spambots get through, so, expect an improved system for readers to post comments in the near future. This website runs on mostly on PHP software, so I would want to have a PHP version to use on this website.
