Appendix D. Managing Sessions in the Database Tier

In Chapter 8 we discussed the development of session-based applications using the PHP session management features. In this appendix, we:

• Discuss the motivation for storing session variables in the database tier of a web database application

• Show how PHP session handlers are written to implement user-defined methods

• Develop a fully functional set of PHP handlers that use a table in a MySQL database to store session variables
