Please note that “Hello Philippines” application is an only a basic example of facebook application, like we always do in some programming language we start our programming by saying “Hello World” output.

Here we will start our development in saying “Hello Philippines” with user picture, some basic information and link to facebook profile.

To start our application development we need to download the following facebook client libraries which is PHP 5.

Extract the file to your www folder or to your sub domain root folder sample the “Hello Philippines” folder is on http://www.helloapp.facebookgarage.ph where technically http://www.facebookgarage.ph/helloapp/ – folder
