This PHP class inserts a small piece of HTML code into your form - an expression consisting of two random numbers, one text input field for user's answer, and one hidden field with the hashcode. When user submits the form with the answer, the answer is being hashed and compared to the security code that has been submitted as well. This way you can easily protect your forms from the spambots.Visit publisher site: MathGuard
