专家网络APIs与PHP：eBay、Google、Paypal、Amazon、Fedex plus Yahoo与Netscape Web Feeds

As the only book that details how to integrate different APIs and web feeds in PHP so websites can leverage content from eBay, Google, PayPal, Amazon, and FedEx, this hands-on guide takes you step by step through each stage of the API process. Experienced PHP programmer Paul Michael Reinheimer walks you through the production and consumption angles of web feeds and discusses XML-feeds so that you can access one of the fastest growing trends on the web. With real-world examples covering everything from basic test implementations to integration with existing sites, you'll learn how to produce and document your own APIs, which will allow you to expand your sites and may even prompt you to re-examine how you structure your code.
