PHPIDS is a security PHP project which aims to provide a security application layer to protect any PHP web application. Using PHPIDS you will be able to see who is attacking your site and how, while keeping your project safe. The application is simple, fast and easy to use. Released open source under LGPL.
The IDS neither strips, sanitizes nor filters any malicious input, it simply recognizes when an attacker tries to break your site and reacts in exactly the way you want it to. Based on a set of approved and heavily tested filter rules any attack is given a numerical impact rating which makes it easy to decide what kind of action should follow the hacking attempt. This could range from simple logging to sending out an emergency mail to the development team, displaying a warning message for the attacker or even ending the user
