In conjunction with some of the folks over at Microsoft Cal Evans has created a search wrapper around the Bing search engine's API to make interacting with it from your PHP applications simpler.

Back in March I had the opportunity to work on a project for Microsoft that is now coming to light. I was tasked with writing a PHP wrapper for the Bing API that Microsoft has been building. I've written API wrappers before and it is either a fun experience or it is a nightmare, depending on whether the API is easy to work with. I am pleased to report that the Bing Search API is well thought out and very easy to work with. For PHP developers, I am hoping that what I am about to show you makes it even easier.

You'll need an API key to use the interface, but the rest is simple. You just create an instance of the search object, pass it a query and sun the "search" method to return the results. Cal has an example snippet of code in his blog.
