Captcha Numbers can generate images for use in CAPTCHA based validation tests (Completely Automated Public Turing test to tell Computers from Humans Apart). It is an improved version of the Captcha Numbers class originally written by Hadar Porat.

This version can generate a random text string that includes letters and digits. Captcha Numbers can also display each of text characters in different vertical positions randomly defined.

The colors of the grid and the text characters alternate to make it more difficult for robots to guess what is the text written in the image. Next to the class PHP file create a folder fonts and place TTF in order to use the random fonts feature.
