Get Everything Here :

In this tutorial I want to show you how to connect App Inventor to a MySQL database using PHP. I tried to keep everything as simple as possible while at the same time teaching enough so that you can do anything.

You’ll be able to submit to, update and then receive a CSV file from the database using the PHP files below. You’ll also be able to limit access to data simply by creating a different PHP file for each person that would need to access the database.
