It's the book everyone's talking about and the entire PHP community should by! Okay, really, there's a few blog posts about it, but it's definitely not one to pass up if you need a quality recource on using web APIs in PHP - Paul Reinheimer's "Professional Web APIs with PHP: eBay, Google, Paypal, Amazon, FedEx plus Web Feeds".

Chris Shiflett comments on his blog that, though he hasn't read it yet:

I know Paul has been working on it for well over a year, and it has already received a positive review from Nathan Smith.

The review gives praise to the book, noting that it provides good examples and helpful tutorials for each of the APIs talked about. The book covers its subject well without trying to "spread itself too thin" by including too much and not focusing on its core - APIs like eBay, Google, FedEx, Flickr, even the National Weather Service.

Even Paul himself comments on the occasion, mentioning what his intentions for the book were and how it changed along the way.
