What are some best practices for integrating multiple payment methods, such as credit cards, into a PHP website?

Integrating multiple payment methods, such as credit cards, into a PHP website requires creating a flexible and secure payment processing system. One best practice is to use a payment gateway like Stripe or PayPal that supports multiple payment methods and provides easy integration with PHP websites. Additionally, storing sensitive payment information securely and following PCI compliance standards is crucial to protect customer data.

// Example code snippet using the Stripe PHP library to integrate credit card payments

require 'vendor/autoload.php'; // Include the Stripe PHP library

\Stripe\Stripe::setApiKey('sk_test_1234567890'); // Set your secret API key

$paymentIntent = \Stripe\PaymentIntent::create([
  'amount' => 1000,
  'currency' => 'usd',
  'payment_method_types' => ['card'],
]);

echo json_encode(['client_secret' => $paymentIntent->client_secret]);
