In this tutorial we discuss the techniques used to build web database applications that authenticate, authorize, and protect the data that is transmitted over the Web. The topics covered in this tutorial include:

- How HTTP authentication works and how it can be used with Apache and PHP;
- Writing PHP scripts to manage user authentication and authorization;
- Writing PHP scripts that authenticate users against a table in a database;
- The practical aspects of building session-based web database applications to authenticate users, including techniques that don't use HTTP authentication;
