lindylex Posted July 14, 2008 Share Posted July 14, 2008 I need to implement a graphic string that a user must enter to send the contents of a form. I have 3 questions. 1. What is this validation called? 2. Ho can I do this with PHP? 3. Can you point me to a location where this technique is explained?
