On the Tiger Heron blog, there's a continuation of the series that Tony Freixas has been writing to following the beginning steps of working with PHP. First there was the download/install, then setting up a development environment. This time, he actually gets around to writing a bit of basic code.
Specifically, I will describe how I boot my PHP scripts and why I boot them the way I do. Part 1 shows how my requirements for code portability and maintainability influence the boot process. Part 2 will go into more detail about the specific steps executed by the boot code.
His basic task for the first example is to make a templating sort of system, calling a Navigation class to output links in list items. He outlines the goals of the project, what he's found for his current solution and some alternatives he's discovered along the way.
