CAPTCHA - A captcha is a test used to distinguish a human from a computer (machine).
The user is asked to recognize a distorted text to prevent automated spamming.
The goal is to generate and grade tests that most humans can pass, but current computer programs can't pass. In Zip file you can find 2 PHP script.
The first creates a static JPEG image with easily and fully customizable features,
as you can see in this page. The second is able to create an animated gif showing a sum, always partially visible.
Here you can find 3 working examples (Guestbook, Shoutbox, Form mailer).
