Why You Should Read This Book This book will teach you how to create interactive websites from the simplest order form through to complex, secure e-commerce sites or interactive Web 2.0 sites.What’s more, you’ll learn how to do it using open source technologies. This book is aimed at readers who already know at least the basics of HTML and have done some programming in a modern programming language before but have not necessarily programmed for the Internet or used a relational database.

What You Will Learn from This Book Reading this book will enable you to build real-world, dynamic websites. If you’ve built websites using plain HTML, you realize the limitations of this approach. Static content from a pure HTML website is just that—static. It stays the same unless you physically update it.Your users can’t interact with the site in any meaningful fashion. Using a language such as PHP and a database such as MySQL allows you to make your sites dynamic: to have them be customizable and contain real-time information. We have deliberately focused this book on real-world applications, even in the introductory chapters.We beg
