Currency Formatting with Laravel's Enhanced Number Helper

Laravel's Number helper now supports configurable default currencies, simplifying price formatting across different regions and use cases. This enhancement is particularly valuable for applications serving international customers or handling transactions in multiple currencies. Instead of manually managing currency symbols and formats, you can now leverage Laravel's built-in formatting with configurable defaults.

use Illuminate\Support\Number;
// Set application-wide default
Number::useCurrency('EUR');
// Format with default
$price = Number::currency(1000); // €1,000.00
// Temporary override
$usdPrice = Number::currency(1000, in: 'USD'); // $1,000.00

Here's an example of implementing a multi-regional checkout system:

<?php
 
namespace App\Services;
 
use App\Models\Order;
use Illuminate\Support\Number;
 
class PricingService
{
    public function formatOrderPrices(Order $order, string $displayCurrency)
    {
        return Number::withCurrency($displayCurrency, function() use ($order) {
            return [
                'subtotal' => Number::currency($order->subtotal),
                'tax' => Number::currency($order->tax),
                'shipping' => Number::currency($order->shipping_cost),
                'total' => Number::currency($order->total),
                'savings' => $this->calculateDiscounts($order)
            ];
        });
    }
 
    private function calculateDiscounts(Order $order): array
    {
        return [
            'bulk_discount' => Number::currency($order->bulk_discount),
            'loyalty_savings' => Number::currency($order->loyalty_discount),
            'total_saved' => Number::currency(
                $order->bulk_discount + $order->loyalty_discount
            )
        ];
    }
}

The Number helper's enhanced currency formatting capabilities streamline multi-currency support in Laravel applications. It provides flexibility for both application-wide defaults and context-specific currency formatting, making it easier to handle international pricing requirements.
