In this new article from the PHP DevCenter on the O'Reilly site today, they provide an introduction to a concept that PHP developers just starting out will definitely need for their future applications - sessions and state management.

MVC Frameworks, such as WASP, provide a solid jumping-off point for entry-level programmers to produce strong, well-formed code. The framework simplifies such things as creating a page (using a kind of page object) and creating or searching for data (using database table objects).

However, probably the most difficult concept for novice PHP programmers to grasp is handling their application's state and session data. This article will address that issue by providing a simple strategy for state management using the WASP framework.

They startprevious article for an introduction.

The O'Reilly site, ONLamp.com, has a new tutorial posted today - a look at how to simplify your PHP development with WASP (Web Application Structure for PHP).

WASP (Web Application Structure for PHP) is a three-tier framework built on PHP 5. Lately, more software engineers are moving from cumbersome "enterprise" languages such as Java and C# to languages such as Python and Ruby and PHP. With version 5, PHP has finally reached the point where these developers can feel at home in what used to be considered a hacker's language. By demonstrating that it is possible to create and use complicated, "enterprise-class" frameworks effectively in PHP 5, WASP will help more developers make the switch.

They look at working with WASP 1.1 to create a project (in this case, a ToDo list), build out its properties, setting up the model/view/controller structure for the site, and wrap it all up with the interface on top (and the interaction with the framework it needs). The article walks you through every step of the way, too, giving clear code examples and explaining what everything is doing...
