[Free] New PHP CAPTCHA Script: Block Spam from Your Contact Forms
A new CAPTCHA script has been added to the Free PHP CAPTCHA Scripts page. The script allows you to add a test to your contact forms to make sure that the person submitting the form is a human and not a spam program.
Note: for those who would rather not modify your own PHP scripts by hand, you may prefer to use my step-by-step tutorial on How to Add a CAPTCHA Test to Your Feedback Form which uses a different set of (free) programs to do the job.
