Accessing Locale and Currency Defaults in Laravel

Laravel enhances Number facade, adds a convenient way to get the default locale and currency settings, and simplifies the internationalization of the application. These new features simplify the locale and currency formatting process and are especially useful when building applications for users in different regions.

The following code shows how to quickly access the default settings:

use Illuminate\Support\Number;
// 快速访问默认值
$locale = Number::defaultLocale();
$currency = Number::defaultCurrency();

Let's look at a practical example of an international order processing system:

<?php namespace App\Services;

use App\Models\Order;
use Illuminate\Support\Number;
use App\Events\OrderProcessed;

class OrderProcessor
{
    public function formatOrderSummary(Order $order, ?string $userLocale = null)
    {
        $locale = $userLocale ?? Number::defaultLocale();
        $currency = $order->currency ?? Number::defaultCurrency();
        return [
            'order_number' => $order->reference,
            'subtotal' => Number::currency($order->subtotal, in: $currency),
            'tax' => Number::currency($order->tax, in: $currency),
            'total' => Number::currency($order->total, in: $currency),
            'formatted_date' => $order->created_at->locale($locale)->isoFormat('LLLL'),
            'meta' => [
                'display_locale' => $locale,
                'currency' => $currency,
                'exchange_rate' => $this->getExchangeRate(
                    from: Number::defaultCurrency(),
                    to: $currency
                )
            ]
        ];
    }

    protected function getExchangeRate(string $from, string $to): float
    {
        // 汇率计算逻辑
        return 1.0;
    }
}

These new helper methods simplify access to the application's default locale, making it easier to handle international formats and currency displays.
