The Bing Search Library for PHP allows you to easily use Bing’s API to fetch search results and use in your own PHP application.
The library for PHP is designed to give PHP developers an object-oriented interface to access the Bing API.
It supports fluent interfaces in PHP so that options can be easily chained together for readability.
The heart of the library is the MsftBingSearch class. It supports all of the options available for searching web and images that are defined in the API.
The Bing API is easy to work with, powerful, and since Google doesn’t give you access to this information from an API, unique.
