Representational State Transfer (REST) is a form of software architecture; systems that follow it are often called RESTful. It is the architectural style that drives the World Wide Web and RESTful web services to use simple protocols already familiar to web developers.

This book helps bridge the gap between understanding the basic concepts of REST architectural style or approach and implementing them in day-to-day work. This book will walk users through PHP tools, libraries and techniques for working with RESTful web services and will also teach them to use other RESTful services from their PHP applications.

Users will learn how to make their own PHP applications accessible to other applications through a RESTful API and also consume RESTful web services, from leading APIs such as Flickr, and Yahoo Web Search. With the help of a case study, users will learn to design a RESTful PHP service, and also create clients to consume the service.
