CAPTCHAs are a security measure for blocking automated form bots and is one of the best spam filters around.
"A simple PHP CAPTCHA script" creates such a CAPTCHA system via PHP and its GD library.
The library simply generates a random text on top of a non-uniform background using a non-standard font.
This text is very hard to parse and break for spamming bots but can easily be read by humans.
