数字韩元与eKRW的区别

PHP数字格式处理

韩元格式化函数

<?php
class KoreanWonFormatter {
    /**
     * 格式化韩元金额
     */
    public static function formatKRW($amount, $includeSymbol = true) {
        $formatted = number_format($amount, 0, '.', ',');
        return $includeSymbol ? "₩{$formatted}원" : $formatted;
    }
    /**
     * 韩元汉字大写（用于正式文件）
     */
    public static function toKoreanHanja($amount) {
        $units = ['', '일', '이', '삼', '사', '오', '육', '칠', '팔', '구'];
        $levels = ['', '십', '백', '천', '만', '억', '조'];
        // 简化的转换逻辑
        if ($amount == 0) return '영';
        return '₩' . number_format($amount) . '원';
    }
    /**
     * 创建韩元金额对象
     */
    public static function createMoney($amount) {
        return new KoreanMoney($amount);
    }
}
class KoreanMoney {
    private int $won;
    public function __construct(int $won) {
        $this->won = $won;
    }
    public function add(KoreanMoney $other): KoreanMoney {
        return new KoreanMoney($this->won + $other->won);
    }
    public function subtract(KoreanMoney $other): KoreanMoney {
        return new KoreanMoney($this->won - $other->won);
    }
    public function multiply(float $factor): KoreanMoney {
        return new KoreanMoney((int)round($this->won * $factor));
    }
    public function __toString() {
        return KoreanWonFormatter::formatKRW($this->won);
    }
}
// 使用示例
echo KoreanWonFormatter::formatKRW(1000000);  // ₩1,000,000원
echo KoreanWonFormatter::formatKRW(50000, false);  // 50,000

eKRW(电子韩元)处理

基础区块链交互

<?php
class EKRWHandler {
    private string $nodeUrl;
    private string $contractAddress;
    public function __construct(string $nodeUrl, string $contractAddress) {
        $this->nodeUrl = $nodeUrl;
        $this->contractAddress = $contractAddress;
    }
    /**
     * 检查eKRW余额
     */
    public function checkBalance(string $walletAddress): float {
        // 实际应调用区块链API
        $endpoint = "{$this->nodeUrl}/api/v1/balance";
        $payload = [
            'contract' => $this->contractAddress,
            'address' => $walletAddress
        ];
        // 模拟返回
        return $this->simulateBalanceCheck($walletAddress);
    }
    /**
     * 发送eKRW交易
     */
    public function sendEKRW(
        string $fromPrivateKey,
        string $toAddress,
        float $amount
    ): array {
        // 验证交易
        if ($amount <= 0) {
            throw new InvalidArgumentException("金额必须大于0");
        }
        // 韩元最小单位是1원（整数处理）
        if (fmod($amount, 1) != 0) {
            throw new InvalidArgumentException("eKRW最小单位为1원");
        }
        // 构建交易（实际应用需要签名）
        $tx = [
            'from' => '주소', // 实际应从私钥推导
            'to' => $toAddress,
            'amount' => (int)$amount,
            'timestamp' => time(),
            'type' => 'eKRW_TRANSFER'
        ];
        return $this->broadcastTransaction($tx);
    }
    /**
     * 韩元与eKRW兑换（1:1汇率）
     */
    public function convertKRWtoEKRW(float $krwAmount): float {
        // 固定1:1汇率（实际可能有差异）
        return $krwAmount;
    }
    private function broadcastTransaction(array $tx): array {
        // 模拟发送到eKRW网络
        return [
            'success' => true,
            'tx_hash' => '0x' . bin2hex(random_bytes(32)),
            'block_number' => random_int(1000000, 9999999),
            'timestamp' => time()
        ];
    }
    private function simulateBalanceCheck(string $address): float {
        // 模拟余额（实际应查链上数据）
        return 0.0;
    }
}

完整示例：韩元支付系统

<?php
require_once 'vendor/autoload.php'; // 如果使用Composer
class KoreanPaymentSystem {
    private array $transactions = [];
    private EKRWHandler $ekrwHandler;
    public function __construct(EKRWHandler $handler) {
        $this->ekrwHandler = $handler;
    }
    /**
     * 处理支付
     */
    public function processPayment(
        float $amount,
        string $paymentMethod = 'KRW',
        array $customerInfo = []
    ): array {
        // 金额验证
        if ($amount <= 0) {
            throw new InvalidArgumentException("金额无效");
        }
        // 记录交易
        $tx = [
            'id' => uniqid('TXN_'),
            'amount' => $amount,
            'method' => $paymentMethod,
            'customer' => $customerInfo['name'] ?? '未知',
            'timestamp' => date('Y-m-d H:i:s'),
            'status' => 'pending'
        ];
        try {
            if ($paymentMethod === 'eKRW') {
                // 电子韩元支付
                $result = $this->ekrwHandler->sendEKRW(
                    $customerInfo['private_key'],
                    $customerInfo['merchant_address'],
                    $amount
                );
                $tx['tx_hash'] = $result['tx_hash'];
                $tx['status'] = 'completed';
            } else {
                // 传统韩元支付（模拟）
                $this->simulateBankTransfer($amount);
                $tx['status'] = 'completed';
            }
            $this->transactions[] = $tx;
            return [
                'success' => true,
                'transaction' => $tx,
                'message' => "₩" . number_format($amount) . "원 결제 완료"
            ];
        } catch (Exception $e) {
            $tx['status'] = 'failed';
            $tx['error'] = $e->getMessage();
            $this->transactions[] = $tx;
            return [
                'success' => false,
                'transaction' => $tx,
                'message' => "결제 실패: " . $e->getMessage()
            ];
        }
    }
    private function simulateBankTransfer(float $amount): void {
        // 模拟银行转账
        usleep(100000); // 100ms延迟
    }
    /**
     * 生成韩元收据
     */
    public function generateReceipt(array $tx): string {
        $format = <<<RECEIPT
━━━━━━━━━━━━━━━━━━━━━
  영수증 (RECEIPT)
━━━━━━━━━━━━━━━━━━━━━
  거래번호: %s
  일시: %s
  금액: ₩%s원
  방법: %s
  고객: %s
  상태: %s
━━━━━━━━━━━━━━━━━━━━━
RECEIPT;
        return sprintf(
            $format,
            $tx['id'],
            $tx['timestamp'],
            number_format($tx['amount']),
            $tx['method'],
            $tx['customer'],
            $tx['status']
        );
    }
}
// 使用示例
$handler = new EKRWHandler('https://ekrw-node.kr', '0xContract123...');
$payment = new KoreanPaymentSystem($handler);
$customer = [
    'name' => '김철수',
    'private_key' => '0x...',
    'merchant_address' => '0xMerchant...'
];
$result = $payment->processPayment(50000, 'eKRW', $customer);
echo $payment->generateReceipt($result['transaction']);

常用函数总结

// 韩元数值处理
$amount = 1000000;
echo number_format($amount, 0, '.', ',');           // 1,000,000
echo sprintf("₩%s원", number_format($amount, 0));   // ₩1,000,000원
// eKRW验证
function validateEKRWAmount($amount): bool {
    return is_numeric($amount) && $amount > 0 && fmod($amount, 1) == 0;
}
// 韩元转英文(百万)
function krwToMillions($amount): string {
    return sprintf("%.2f백만원", $amount / 1000000);
}

注意事项

1. 精度问题：使用整数存储韩元（最小单位1원）
2. 汇率：eKRW与KRW通常1:1，但需确认
3. 合规性：处理CBDC需遵循韩国央行规定
4. 安全性：私钥管理非常重要

需要更具体的实现细节吗？如需集成银行API或区块链交互,请告知！
