我来帮您了解PHP项目中处理数字韩元(KRW)和电子韩元(eKRW)的相关实现。
数字韩元与eKRW的区别
| 类型 | 说明 | 特点 |
|---|---|---|
| KRW (韩元) | 传统韩元货币 | 法币，物理货币+银行数字记账 |
| eKRW (电子韩元) | 韩国央行CBDC | 数字货币，区块链技术 |
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
- 精度问题：使用整数存储韩元（最小单位1원）
- 汇率：eKRW与KRW通常1:1，但需确认
- 合规性：处理CBDC需遵循韩国央行规定
- 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！
