Nowaday in Web 2.0 realm, AJAX become primary need for web developer to create a dynamic web applications. Not only web developer, but also spammer getting more dynamic and clever
Usually they fill in comment box or input user to put their junk content like backlinks. To avoid this, it’s commonly to used CAPTCHA since they effective enough to blocked spammer.
But now it’s Web 2.0! AJAX in everywhere. So let’s create a simple AJAX Captcha to accomodate this. First searched for Google and found it, there’s enough resource to make a improvisation with this stuff (How to Create CAPTCHA Protection using PHP and AJAX and FunkyAJAX). I tried at home but no one of them have a complete feature but still simple
So i combine all resource and build this one, simple but have a full feature that i wanted!
