PHP, MySQL & Stripe API Payment App – Part 1 – Download



In this video series we will build a PHP payment page that accepts credit cards using the stripe API and also stores the data in a MySQL database using PDO. We will be creating tables and models for customers and transactions to store them in the database and retrieve them within the app.
