This tutorial will demo to you how to create a facebook apps and using facebook api (PHP SDK)
We’re using Facebook API v2.6.
Step 1: Create your facebook account!
Step 2: Create your facebook apps, follow my instructions:
Login https://developers.facebook.com/
Create apps by “Add a new app”
Enter the name “Get Info Email List”
See below the options (this option maybe change up to Facebook development)
See the config apps:
Basic Settings:
Use Canvas Page name:
https://apps.facebook.com/email_list_app
Secure Canvas URL:
https://vilh.herokuapp.com/
Site URL:
https://vilh.herokuapp.com/
Valid OAuth redirect URLs:
https://vilh.herokuapp.com/callback.php
Advanced Settings:
Step 3: Build Source code
Download PHP SDK from the above link, after that use this link into your projects. Create two files with index.php and callback.php, set up your facebook SDK folder
Rename to facebook-sdk-v5
In source code remember “always define the SDK source with /facebook-sdk-v5/”
Inside facebook-sdk-v5
index.php
<?php
if(!session_id()) {
session_start();
}

If you don’t have hosting for test, you can use Heroku cloud platform to test it! By upload to heroku. You can see this link (This can help you deploy any project to Heroku)
If you have any question or feedback, leave your comment, we can discuss about it!
