This package can show a CAPTCHA image with validation question and answers.
It can generate an image with message that presents a question that the user needs to answer to pass the CAPTCHA validation challenge.
The main class also generates button images with text that present different answers for the challenge question.
The correct answer is stored in one of several possible containers for subsequent validation. Currently it provides container classes for storing answers in session variables or APC cache keys.
The challenge question and answers are redefinable. The presentation of the question and answer is defined by custom template scripts.

CAPTCHA validation is often used to prevent automated access of robot scripts to sites that are intended to be accessed only by real human users. Most solutions tend to challenge the user by asking him to respond to a question, which often is something written or drawn in a graphical image. This class goes further and makes it more difficult for robots to break by presenting either the challenge and the possible responses as images. Manuel Lemos |
