This is a sample app showing use of the Facebook Graph API, written in PHP, designed for deployment to Heroku.

Configure Apache with a VirtualHost that points to the location of this code checkout on your system.

Create an app on Facebook and set the Website URL to your local VirtualHost.

Copy the App ID and Secret from the Facebook app settings page into your VirtualHost config, something like:

<VirtualHost *:80>
    DocumentRoot /Users/adam/Sites/myapp
    ServerName myapp.localhost
    SetEnv FACEBOOK_APP_ID 12345
    SetEnv FACEBOOK_SECRET abcde
</VirtualHost>

Restart Apache, and you should be able to visit your app at its local URL.

The easiest way to deploy is to create an app on Facebook and click Cloud Services -> Get Started, then choose PHP from the dropdown. You can then git clone the resulting app from Heroku.

If you prefer to deploy yourself, push this code to a new Heroku app on the Cedar stack, then copy the App ID and Secret into your config vars:

heroku create --stack cedar
git push heroku master
heroku config:add FACEBOOK_APP_ID=12345 FACEBOOK_SECRET=abcde

Enter the URL for your Heroku app into the Website URL section of the Facebook app settings page, hen you can visit your app on the web.
