Facebook Automatic Post

You will provide 1 php file that does the following:
First PHP function inside the file
1) Gets text + image from a DB table
2) Creates a new post on a Facebook page that contains the text + image that you got from the DB

Second PHP function inside the file
1) Gets text + Youtube URL from a DB table
2) Creates a new post on a Facebook page that contains the text + Youtube URL that you got from the DB

The PHP file needs to be well documented through comments plus you will provide detailed steps with screen shots on how to create the Facebook App, its id, its secret and its token plus how to make sure that this token doesn't expire so that I can create the needed Facebook App, link it with the PHP code and then run the PHP script to do the functionality described above

You need to use the latest Facebook SDK with the latest Graph API

If you didn't deliver the script as per the above description or it was not documented or you didn't provide the mentioned steps to create the Facebook App or the script didn't work as intended then the project is not complete and you need to complete it before you receive the payment
