1. How to Perform PHP Form Human Check using a Pad with Codes for Users to Demonstrate They Are Not Robots
Some times it is necessary that applications verify if a user accessing the site is a real human, rather than a robot script that its trying to abuse from the system resources.
This class provides a solution that consists of a key pad that displays on a Web page. Then the users need to click or touch on keys that appear on the screen to demonstrate that they are real humans to enter the right codes by the right order.
