Turing Number

This script generates and checks a turing number. A turing number is a number the user has to read and copy in order to be able to validate a form. This avoids automated submissions (bots...). There is a version using a MySQL database, and another version (available on the site - see the link at the top of the script page) that uses sessions instead, so you don''t need MySQL on your server.
