PHP Web 2.0 Mashup Projects
Chapter 1 provides an overview of mashups: what a mashup is, and why you would want one.
In Chapter 2 we create a basic mashup, and go shopping. We will simply look up products on Amazon.com based on the Universal Product Code (UPC). To do this, we cover two basic web services to get our feet wet — XML-RPC and REST. The Internet UPC database is an XML-RPC-based service, while Amazon uses REST.
We will create code to call XML-RPC and REST services. Using PHP's SAX function, we create an extensible object-oriented parser for XML. The mashup covered in this chapter integrates information taken from Amazon's E-commerce Service (ECS) with the Internet UPC database.
