PHP项目集成方案
注意事项

我理解您想了解关于“数字东加勒比元”（Digital Eastern Caribbean Dollar，简称DXDC或DCash）与“eXCD”之间的关系，以及它们在PHP项目中的应用。

数字东加勒比元(DXDC)与eXCD的关系

eXCD 实际上是 东加勒比元（XCD） 的数字版本，即：

XCD = 东加勒比元（传统法定货币，ISO代码）
eXCD = 电子版/数字版东加勒比元（Digital XCD）
DXDC = Digital XCD Currency（官方名称）

eXCD 就是数字东加勒比元的简称或非正式称呼。

PHP项目集成方案

货币单位处理

<?php
class DXCCurrency
{
    private string $code = 'XCD';
    private string $digitalCode = 'DXDC';
    private string $symbol = 'EC$';
    private string $digitalSymbol = 'eXCD';
    // 最小单位：cents（1 XCD = 100 cents）
    private int $decimalPlaces = 2;
    public function formatAmount(float $amount, bool $isDigital = false): string
    {
        $symbol = $isDigital ? $this->digitalSymbol : $this->symbol;
        return $symbol . ' ' . number_format($amount, $this->decimalPlaces, '.', ',');
    }
    public function convertToDigital(float $traditionalAmount): float
    {
        // 1:1 兑换率（数字版本与传统版本等值）
        return $traditionalAmount;
    }
}

支付集成示例

<?php
class DigitalECCPayment
{
    private string $apiEndpoint = 'https://api.digitalecb.com/v1';
    private string $apiKey;
    public function __construct(string $apiKey)
    {
        $this->apiKey = $apiKey;
    }
    public function createPayment(float $amount, string $walletAddress): array
    {
        // 创建数字东加勒比元支付
        $paymentData = [
            'amount' => $amount,
            'currency' => 'DXDC',  // 或 'eXCD'
            'wallet' => $walletAddress,
            'timestamp' => time(),
            'merchant_id' => $this->getMerchantId()
        ];
        // 签名验证
        $signature = $this->generateSignature($paymentData);
        $paymentData['signature'] = $signature;
        return $this->sendRequest('POST', '/payments', $paymentData);
    }
    private function generateSignature(array $data): string
    {
        ksort($data);
        $dataString = http_build_query($data);
        return hash_hmac('sha256', $dataString, $this->apiKey);
    }
}

钱包管理类

<?php
class DXDCWallet
{
    private string $walletId;
    private float $balance;
    private array $transactions = [];
    private string $currencyType; // 'traditional' 或 'digital'
    public function __construct(string $walletId, string $currencyType = 'digital')
    {
        $this->walletId = $walletId;
        $this->currencyType = $currencyType;
    }
    public function transfer(float $amount, string $toWalletId): bool
    {
        if ($this->balance < $amount) {
            throw new \Exception('Insufficient DXDC balance');
        }
        $transaction = [
            'id' => uniqid('dxdc_'),
            'from' => $this->walletId,
            'to' => $toWalletId,
            'amount' => $amount,
            'currency' => 'DXDC',
            'timestamp' => date('Y-m-d H:i:s'),
            'status' => 'pending'
        ];
        // 调用区块链API进行转账
        $this->submitTransaction($transaction);
        $this->balance -= $amount;
        $this->transactions[] = $transaction;
        return true;
    }
    public function getBalance(): float
    {
        // 从区块链节点获取实时余额
        return $this->balance;
    }
}

汇率转换器

<?php
class DXCDExchangeRate
{
    private string $apiUrl = 'https://api.exchangerate-api.com/v4/latest/XCD';
    private array $cachedRates = [];
    public function convertFromUSD(float $usdAmount): float
    {
        // 1 USD ≈ 2.70 XCD (数字版本同等)
        $rate = $this->getRate('USD');
        return $usdAmount * $rate;
    }
    public function convertToUSD(float $dxdcAmount): float
    {
        $rate = $this->getRate('USD');
        return $dxdcAmount / $rate;
    }
    private function getRate(string $currency): float
    {
        if (!isset($this->cachedRates[$currency])) {
            $response = file_get_contents($this->apiUrl);
            $data = json_decode($response, true);
            $this->cachedRates = $data['rates'];
        }
        return $this->cachedRates[$currency] ?? 2.70; // default rate
    }
}
