The Facebook Platform allows anyone to build social applications on Facebook and the Web. To enable you to build such applications, Facebook offers an extensive collection of core and advanced APIs and SDKs.  We have tried to develop some working examples of core features provided by Facebook API. Many times when we search on internet for a particular solution we found very complex example which is very difficult to understand so our purpose is to provide working example at a very basic level so that anyone can understand the implementation of Facebook API easily.
