// This code snippet demonstrates how to optimize a price calculation function by using efficient algorithms and error handling

function calculatePrice($quantity, $unitPrice) {
    // Validate input parameters
    if (!is_numeric($quantity) || !is_numeric($unitPrice)) {
        return 'Invalid input parameters';
    }

    // Calculate total price
    $totalPrice = $quantity * $unitPrice;
