This is part 4 of a multi-part series on the design of a complete application framework written in PHP. In part 1, we covered the basic class structure of the framework and laid out the scope of the project. The second part described methods for managing users and session data. The third part described a practical implementation of page templates. In this fourth and final section, we will expand on our implementation of page templates to provide the web application persistent form data capabilities.
