This book offers an incredible guide and reference to everything you can do with XML and PHP. Not only does this book cover the fundamentals of XML, such as SAX, DOM, XPATH and XSLT, but it covers rich topics like Apache Xindice, advanced XML storage techniques, XML-RPC, SOAP and a variety of both functional and object-oriented approaches to all these concepts.
At IBM, we have always been a strong advocator of PHP for being the perfect language for connecting to databases over the web and offering dynamic content and services. It's simple, elegant, easy and effective. Even further, IBM has always explored XML within PHP and has advocated the use of PHP with our DB2 product.
This book takes your existing PHP skills in HTML and databases and brings them to a whole new level. By taking your current knowledge and adding XML into the mix, this book will truely help you think creatively and create more complex applications. Even given all the hype around "Web Services", this book takes an incredible look into XML-RPC and SOAP. The authors have done, in my opinion, a fantastic job.
I give this book 5 stars because it truely deserves such a rating. The book is absolutely solid. If you want to learn anything from the fundamentals of XML all the way to Web Services, this book will show you the path and everything in-between.
