After nearly a year’s work, my book on the building of a Content Management System using PHP was finally published in June 2008. Although when I started working on new code for a CMS, most hosting used PHP 4, it seemed clear that such a substantial development should be done in the more advanced PHP 5. One factor was to take advantage of the greatly improved object model, which enabled the CMS design to be much more OO. So the book came to be called “PHP 5 CMS Framework Development” since it talks mainly about my ideas for how best to create the real heart of a CMS. Although it is illustrated with a particular CMS, my Aliro product, the ideas should be applicable to any CMS development. As I review other projects, it is interesting to see many parallels with my code, and also some interesting differences.
