php-omnipayHow do I use Omnipay with PHP?

Omnipay is a payment processing library for PHP. It provides a simple and consistent interface for processing payments with various payment gateways.

To use Omnipay with PHP, you first need to install it via Composer. Once installed, you can then create a gateway instance and use it to process payments.

For example, to create a gateway instance for Stripe:

$gateway = Omnipay::create('Stripe');
$gateway->setApiKey('YOUR_STRIPE_API_KEY');

You can then use the gateway instance to process payments. For example, to charge a credit card:

$response = $gateway->purchase([
    'amount' => '10.00',
    'currency' => 'USD',
    'card' => $cardData,
])->send();

if ($response->isSuccessful()) {
    echo "Payment was successful!\n";
} else {
    echo "Payment failed.\n";
}

Code explanation

• Omnipay::create('Stripe') - to create a gateway instance for Stripe
• $gateway->setApiKey('YOUR_STRIPE_API_KEY') - to set the Stripe API key
• $gateway->purchase() - to initiate a purchase request
• $response->isSuccessful() - to check if the payment was successful
