I don’t know what it is about Facebook documentation that I find tedious. I feel that their documentation overcomplicates things because they try and cover so much. Anyway, I created a very basic version of how to implement their Authentication API.

Take a look at the simple demo here:

You can checkout the repository here:

There are two main files and they are very self explanatory. ‘index.php’ contains a link to the Facebook OAuth url with the current APP ID, then ‘output.php’ takes the access_token of the authenticated user and outputs a JSON array. Then you can feel free to use the data as you wish
