How can dynamic pricing be implemented in a PayPal integration using PHP?

Dynamic pricing in a PayPal integration using PHP can be implemented by passing the item price as a dynamic variable in the PayPal API request. This allows you to update the price based on various factors such as user input, discounts, or promotions. By dynamically setting the price in the API request, you can ensure that the correct amount is charged to the customer. 

// Set the item price dynamically
$item_price = 50; // This can be set dynamically based on user input or other factors

// Set up the PayPal API request with dynamic pricing
$api_request = [
    'METHOD' => 'SetExpressCheckout',
    'PAYMENTREQUEST_0_AMT' => $item_price,
    // Add other API parameters as needed
];

// Make the API call to PayPal
// This is where you would send the API request and handle the response
