What steps are involved in redirecting a user to the approval_url for PayPal payments in PHP integration?

To redirect a user to the approval_url for PayPal payments in PHP integration, you need to first create a payment object, set up the necessary parameters including the redirect URLs, and then retrieve the approval_url from the payment response to redirect the user to PayPal for payment approval. 

// Create a payment object
$payment = new Payment();
$payment->setIntent('sale')
    ->setPayer($payer)
    ->setTransactions([$transaction])
    ->setRedirectUrls($redirectUrls);

// Create the payment
try {
    $payment->create($apiContext);
    $approvalUrl = $payment->getApprovalLink();
    // Redirect the user to the approval_url
    header("Location: $approvalUrl");
} catch (Exception $e) {
    // Handle any errors
    echo 'Error creating payment: ' . $e->getMessage();
}
