While we are migrated the skeleton of our 1st FB appl to use the PHP SDK in "Learning PHP SDK - Part 1 to 3", we will start migrate other application specific features.

I am using the title "Learning Graph API - Part 1" instead of "Learning PHP SDK - Part 4" because although we are still building our application on the PHP SDK, it actually call Facebook's Graph API behind the scene. Therefore, what we have learnt in the series "Learning Graph API" should be applicable to other client libraries (if they are using Graph API) too.

As a reference, please note the following information:
