This book takes you step-by-step through the process of building a simple content management system with Zend Framework and MySQL. You start by installing Zend Server and the framework. Then you learn to leverage the framework’s components, which manage the system’s design, content, users, and navigation, among many other things. With the base system up and run- ning, you move on to advanced topics such as performance tuning and creating an API for your CMS. Each topic adds to your CMS, building a flexible, stable, and powerful platform on which you can base your real-world projects This book is born from my experience of developing sites using many of the current open source CMS systems. These were adequate for the sort of projects that the CMS developers originally had in mind. Working with cre- ative people, though, I found that even the simplest projects inevitably need some customization. Developing pure custom systems is an obvious solution, but it has a down- side. There are many moving parts in a secure web publishing system, and developing them all from scratch takes far too long, as well as distracting you from writing key business logic. Zend Framework gives you the best of both worlds, letting you build exactly the software you want without ever having to reinvent the wheel.
