How can you improve the readability and organization of PHP code to make it easier to troubleshoot and maintain in the future?

To improve the readability and organization of PHP code, you can follow best practices such as using consistent naming conventions, proper indentation, commenting your code, breaking down complex tasks into smaller functions, and avoiding excessive nesting. By doing so, you can make your code easier to troubleshoot and maintain in the future. 

// Example of improved PHP code with better readability and organization

// Define constants with meaningful names
define('TAX_RATE', 0.15);
define('DISCOUNT_THRESHOLD', 1000);

// Function to calculate total price after tax and discount
function calculateTotalPrice($price, $quantity) {
    $subtotal = $price * $quantity;
    
    if ($subtotal > DISCOUNT_THRESHOLD) {
        $discount = $subtotal * 0.1;
    } else {
        $discount = 0;
    }
    
    $tax = $subtotal * TAX_RATE;
    $total = $subtotal + $tax - $discount;
    
    return $total;
}

// Example usage
$totalPrice = calculateTotalPrice(50, 20);
echo "Total price after tax and discount: $" . $totalPrice;
