What are the potential benefits of using a payment gateway library like Omnipay for handling PayPal transactions in PHP?

Using a payment gateway library like Omnipay for handling PayPal transactions in PHP can provide several benefits. It simplifies the integration process by providing a unified API for multiple payment gateways, including PayPal. This allows for easier maintenance and updates as the library handles any changes in the underlying APIs. Additionally, Omnipay abstracts away the complexities of payment processing, making it easier for developers to focus on their application logic. 

// Example code using Omnipay to handle a PayPal transaction
use Omnipay\Omnipay;

// Initialize the PayPal gateway
$gateway = Omnipay::create('PayPal_Express');
$gateway->setUsername('YOUR_PAYPAL_USERNAME');
$gateway->setPassword('YOUR_PAYPAL_PASSWORD');
$gateway->setSignature('YOUR_PAYPAL_SIGNATURE');
$gateway->setTestMode(true); // Set to false for live transactions

// Prepare the purchase data
$params = [
    'amount' => '10.00',
    'currency' => 'USD',
    'returnUrl' => 'https://example.com/success',
    'cancelUrl' => 'https://example.com/cancel',
];

// Send the purchase request
$response = $gateway->purchase($params)->send();

// Redirect to PayPal for payment
$response->redirect();
