David Goodwin has posted a new book review of a PHP book offered by Packt Publishing (released Sept 22, 2007) - "PHP Web 2.0 Mashup Projects" by Shu-Wai Chow.
Some time ago, Packt publishing sent me this book to review. Here it is, being somewhat overdue!
He talks about the book's contents - the different chapters detailing the different services' APIs, the protocols that are used to talk to those services and the data formats your scripts would have to be able to talk in to communicate. He recommends the book to those looking to get started with mashups specifically, but warns that in some places the book tends to "reinvent the wheel" rather than using classes/packages that already exist.
