PHPEclipse: A User Guide is a quick read. Having already worked with Eclipse for PHP development the book didn't present any drastic or life changing additions to my technique with Eclipse.
The book is greatly geared toward the newest of PHP programmers, ones still looking to make a mark in the world, or those who are looking to escape the claws of another IDE and want to know what Eclipse and PHPEclipse are all about. Shu-Wai does and excellent job of explaining what Perspectives and Views are and how they work together to make up the meat of PHPEclipse.
Each chapter is full of quick information about how to setup a specific aspect of Eclipse to better work with PHP development. Chapters 3 and 4 explain how the IDE displays information about your application to you, and where to look for more information. Chapters 5 through 8 explain different plug-ins (CVS, Debug, Deploying code) and explain how they work integrated with Eclipse. The best part of each of these latter chapters is they explain in detail how to get the particular plugin installed and configured. It was a fresh and welcome look at plugins and how they work.
What peaked my interest in the book were two things. The first was Appendix A which explains more about where to get more plugins and information about the plugins. The second was the overview of Eclipse. A short history and explanation of how Eclipse came to be what it is today. I was particularly interested in the plugin development, which is built right into Eclipse.
Although the book is short, and a quick read, if you are thinking about picking up Eclipse and using it, you should get this book and read through it while you are in the process.
