Overview of this book

The book is structured so that following the chapters in order builds a TYPO3 extension from the ground up. Experienced developers can use individual chapters independently to get only the information that they need. Each chapter is divided so that the first part contains a description and discussion of the topic covered followed by a coding example with explanation of how principles and techniques from the first part are followed in the code. The reader is encouraged not only to read the book but also to look into the discussed classes and actually code the extension while reading the book. This book is for PHP developers who want to develop a TYPO3 extension. It assumes the reader has experience with PHP, XML, and HTML. No prior knowledge about TYPO3 extension programming or the TYPO3 API is presumed.
