What are the considerations and requirements for implementing payment methods like credit card processing and direct debits on a PHP website, especially for cross-border transactions within Europe?

To implement payment methods like credit card processing and direct debits on a PHP website for cross-border transactions within Europe, you will need to consider compliance with regulations such as PSD2, ensuring secure data handling, and integrating with payment gateways that support cross-border transactions. Additionally, you may need to handle currency conversion and international payment methods. 

// Sample PHP code for integrating credit card processing using Stripe

// Include the Stripe PHP library
require_once('vendor/autoload.php');

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

// Create a payment intent
$intent = \Stripe\PaymentIntent::create([
  'amount' => 1000, // amount in cents
  'currency' => 'eur',
  'payment_method_types' => ['card'],
]);

// Handle the payment form submission
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $payment_method = $_POST['payment_method'];

    // Confirm the payment intent with the selected payment method
    $intent->confirm([
        'payment_method' => $payment_method,
    ]);

    // Handle successful payment
    // Redirect or display a success message to the user
}
