/* Charging a Customer

For a customer, you can use the same HTML, CSS, and JS. You just have to change the PHP script. You have to create a Customer object then charge this customer object.

// Get the token from the JS script
$token = $_POST['stripeToken'];

// Create a Customer
$customer = \Stripe\Customer::create(array(
    "email" => "paying.user@example.com",

// Charge the Customer instead of the card
$charge = \Stripe\Charge::create(array(

For the subscription, all you have to do is change the PHP script.

// You only need to create the plan once.
