货币处理核心代码
注意事项

我来帮你分析PHP项目中处理摩洛哥迪拉姆(MAD)与电子迪拉姆(eMAD)的常见方案。

货币处理核心代码

货币格式化类

<?php
class MoroccanCurrencyFormatter {
    /**
     * 格式化金额为MAD显示格式
     */
    public static function formatMAD($amount, $decimals = 2) {
        return number_format($amount, $decimals, ',', ' ') . ' MAD';
    }
    /**
     * 格式化金额为eMAD显示格式
     */
    public static function formatEMAD($amount, $decimals = 2) {
        return number_format($amount, $decimals, ',', ' ') . ' eMAD';
    }
    /**
     * MAD转换为eMAD (1 MAD = 1 eMAD，数值相同但用途不同)
     */
    public static function madToEmad($amount) {
        return (float) $amount;
    }
    /**
     * eMAD转换为MAD
     */
    public static function emadToMad($amount) {
        return (float) $amount;
    }
    /**
     * 金额验证
     */
    public static function validateAmount($amount) {
        if (!is_numeric($amount) || $amount < 0) {
            throw new InvalidArgumentException('Invalid amount value');
        }
        if ($amount > 999999999.99) {
            throw new OverflowException('Amount exceeds maximum limit');
        }
        return true;
    }
    /**
     * 阿拉伯语金额显示
     */
    public static function formatArabic($amount) {
        $arabicDigits = ['٠', '١', '٢', '٣', '٤', '٥', '٦', '٧', '٨', '٩'];
        $formatted = number_format($amount, 2, '.', ',');
        $result = '';
        foreach (str_split($formatted) as $char) {
            if (is_numeric($char)) {
                $result .= $arabicDigits[(int)$char];
            } else {
                $result .= $char;
            }
        }
        return $result . ' درهم';
    }
}
?>

数据库货币字段设计

-- MySQL示例
CREATE TABLE transactions (
    id INT PRIMARY KEY AUTO_INCREMENT,
    amount_mad DECIMAL(15,2) NOT NULL COMMENT '摩洛哥迪拉姆金额',
    amount_emad DECIMAL(15,2) DEFAULT NULL COMMENT '电子迪拉姆金额',
    currency_type ENUM('MAD', 'eMAD') NOT NULL DEFAULT 'MAD',
    exchange_rate DECIMAL(10,6) DEFAULT 1.000000 COMMENT '汇率',
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    INDEX idx_currency (currency_type)
);

税款计算示例

<?php
class TaxCalculator {
    // VAT税率 (20%标准税率)
    const VAT_RATE = 0.20;
    /**
     * 计算含税金额
     * 
     * @param float $exclTax 不含税金额
     * @param string $currency 'MAD' 或 'eMAD'
     * @return array
     */
    public static function calculateWithTax($exclTax, $currency = 'MAD') {
        $vatAmount = $exclTax * self::VAT_RATE;
        $inclTax = $exclTax + $vatAmount;
        return [
            'excl_tax' => $exclTax,
            'vat_rate' => self::VAT_RATE * 100,
            'vat_amount' => $vatAmount,
            'incl_tax' => $inclTax,
            'currency' => $currency,
            'formatted_excl' => MoroccanCurrencyFormatter::formatMAD($exclTax),
            'formatted_incl' => MoroccanCurrencyFormatter::formatMAD($inclTax)
        ];
    }
    /**
     * 支付方式处理
     */
    public static function processPayment($amount, $paymentMethod) {
        switch ($paymentMethod) {
            case 'cash':
                return MoroccanCurrencyFormatter::formatMAD($amount);
            case 'electronic':
                return MoroccanCurrencyFormatter::formatEMAD($amount);
            case 'mixed':
                $cashAmount = $amount * 0.5;
                $emadAmount = $amount * 0.5;
                return [
                    'cash' => MoroccanCurrencyFormatter::formatMAD($cashAmount),
                    'electronic' => MoroccanCurrencyFormatter::formatEMAD($emadAmount),
                    'total' => $amount
                ];
            default:
                throw new InvalidArgumentException('Unsupported payment method');
        }
    }
}
?>

货币转换中间件示例 (Laravel)

<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Http\Request;
class CurrencyMiddleware
{
    /**
     * 处理货币转换请求
     */
    public function handle(Request $request, Closure $next)
    {
        // 检测请求中的货币类型
        $currencyType = $request->header('X-Currency-Type', 'MAD');
        // 存储到请求属性
        $request->attributes->set('currency_type', $currencyType);
        // 自动转换金额参数
        if ($request->has('amount')) {
            $amount = $request->input('amount');
            if ($currencyType === 'eMAD') {
                // eMAD转换为MAD内部处理
                $madAmount = MoroccanCurrencyFormatter::emadToMad($amount);
                $request->merge(['amount_mad' => $madAmount]);
            } else {
                $request->merge(['amount_mad' => $amount]);
            }
        }
        $response = $next($request);
        // 响应中转换货币格式
        if ($response->getStatusCode() === 200 && $response->original) {
            $data = $response->getData(true);
            if (isset($data['amount'])) {
                if ($currencyType === 'eMAD') {
                    $data['formatted_amount'] = MoroccanCurrencyFormatter::formatEMAD($data['amount']);
                } else {
                    $data['formatted_amount'] = MoroccanCurrencyFormatter::formatMAD($data['amount']);
                }
                $response->setData($data);
            }
        }
        return $response;
    }
}
?>

支付网关集成示例

<?php
class CMI_PaymentGateway {
    private $merchantId;
    private $secretKey;
    public function __construct($merchantId, $secretKey) {
        $this->merchantId = $merchantId;
        $this->secretKey = $secretKey;
    }
    /**
     * 创建支付请求
     */
    public function createPayment($amount, $orderId, $currency = 'MAD') {
        $paymentData = [
            'merchantId' => $this->merchantId,
            'orderId' => $orderId,
            'amount' => $amount * 100, // 转换为分
            'currency' => $currency,
            'paymentType' => ($currency === 'eMAD') ? 'ELECTRONIC' : 'CASH',
            'successUrl' => url('/payment/success'),
            'failUrl' => url('/payment/fail'),
            'timestamp' => time()
        ];
        // 生成签名
        $paymentData['signature'] = $this->generateSignature($paymentData);
        return $paymentData;
    }
    /**
     * 生成支付签名
     */
    private function generateSignature($data) {
        ksort($data);
        $signatureString = implode('|', $data);
        return hash_hmac('sha256', $signatureString, $this->secretKey);
    }
}
?>

使用示例

<?php
// 使用示例
try {
    // 格式化金额
    echo MoroccanCurrencyFormatter::formatMAD(1500.50); // "1 500,50 MAD"
    echo MoroccanCurrencyFormatter::formatEMAD(2000.00); // "2 000,00 eMAD"
    // 阿拉伯语显示
    echo MoroccanCurrencyFormatter::formatArabic(1234.56); // "١٢٣٤,٥٦ درهم"
    // 计算税款
    $taxResult = TaxCalculator::calculateWithTax(1000, 'MAD');
    print_r($taxResult);
    // 混合支付
    $mixedPayment = TaxCalculator::processPayment(500, 'mixed');
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
?>
