Beginners in PHP can ensure they are implementing payment system integration correctly in a web shop by using a reliable payment gateway provider, following the documentation provided by the provider, and testing the integration thoroughly before going live. It's important to handle errors gracefully and securely process payment data to protect customer information. 

// Example code snippet for implementing payment system integration in PHP

$paymentGateway = new PaymentGateway('api_key', 'api_secret');

// Process payment for an order
$orderAmount = 100.00;
$paymentResponse = $paymentGateway->processPayment($orderAmount);

// Check if payment was successful
if($paymentResponse['status'] == 'success'){
    // Payment successful, update order status and redirect to thank you page
    updateOrderStatus($orderId, 'paid');
    header('Location: thank_you.php');
} else {
    // Payment failed, display error message to the user
    echo 'Payment failed. Please try again.';
}
