If you haven't already, you may want to start with Part 1 of this topic. Part 2 of my discussion on booting begins with a digression.

Frameworks and libraries

Some time ago, I read an article by Rasmus Lerdorf titled The no-framework PHP MVC framework. It got me thinking about my framework, which at the time I was converting from PHP4 to PHP5.

In the good old days, if you wanted to create re-usable code, you would create a library of related functions or objects. Now, the excitement is all around frameworks. Everyone has one. What is the difference between the two?

Having covered downloading and installing PHP and setting up a development environment, I'm now actually going to talk about writing PHP 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.
