This particular book provides the reader with a comprehensive view of PHP development. I was pleased with the vast amount of topics covered. This book is a very useful tool for developers.

'Pro PHP XML and Web Services' by Robert Richards is a great book to help you learn your way around these technologies. Packing in over 900+ pages, this book gives a broad overview of the subject matter which is outlined here:

01. Introduction to XML and Web Services
02. XML Structure
03. Validation
04. XPath, XPointer, XInclude
05. PHP and XML
06. Document Object Model
07. SimpleXML
08. Simple API for XML
09. XMLReader
10. Extensible Stylesheet Language Transformations
11. Effective and Efficient Processing
12. XML Security
13. PEAR and XML
14. Content Syndication: RSS and Atom
15. Web Distributed Data Exchange
16. XML-RPC
17. Representational State Transfer
18. SOAP
19. Universal Description, Discovery, and Integration (UDDI)
20. PEAR and Web Services
21. Other XML Technologies and Extensions

If you need a book that dives into the XML technology and doesn't look back, this is a nice pickup that gets the job done. Lots of other Apress books I feel are a bit too long, but this book at over 900 pages I have less complaints about. It's solidly written and a nice companion book to have on your bookshelf for anyone that programs with XML.

**** RECOMMENDED

This is first and foremost an XML reference. The author takes the reader through over 100 pages XML background in the first three chapters, then an overview of a few utilities like XPath and XPointer before he touches on PHP. Having provided some grounding in the basics, he then proceeds to develop the use of XML in PHP from the basic topics of DOM (Document Object Model) and XSLT (Extensible Stylesheet Language Transformations) to the more advanced topics of SOAP (Simple Object Access Protocol) and web services.

Along the way Richards introduces the reader to utility classes like SimpleXML, SAX (Simple API for XML), XMLReader. He also touches on PEAR (PHP Extension and Application Repository) utility classes and topics like security, RSS (Really Simple Syndication) and UDDI (Universal Description, Discovery and Integration). The author's examples are reasonably concise and readable; making the necessary points without getting carried away.

The bottom line is that this is a highly effective reference (that means fairly comprehensive, but dry reading; I read cover to cover, but it was relatively tedious) on XML and its varied uses in association with PHP. This is not a book for the newcomer to programming, nor is it a cookbook for examples for the casual programmer/web developer, although the author does provide PEAR examples for connecting with major web services like Amazon, Google and Yahoo (among others). My suggestion for readers is to review what you need of the first 11-12 chapters to ensure a firm grounding in XML, and then hop to the chapters specific to the problem being faced.
P-)

This is a great book in that the author provides comprehensive coverage of a complicated subject, and does it in clear, concise and understandable language. The book should be a promary resource for programmers. I look forward to more contributions from this author.

This book is amazingly well written. The content is organized in an intuitive and logical fashion. The author explains base concepts and progresses into advanced topics, providing consistent depth of coverage along the way. The author's writing and concise examples get the message across on the first reading - unlike some texts that require multiple passes. It's also noteworthy that the Technical Reviewers, Christian Stocker and Adam Trachtenberg, are renowned PHP experts and authors. If you plan to study or work with PHP and XML, this book is a MUST HAVE.
