我来帮你了解PHP项目中有关数字兰特（ZAR）和电子兰特（eZAR）的集成方案。
什么是数字兰特和eZAR？
- 数字兰特 (Digital ZAR)：南非兰特的数字货币形式
- eZAR：南非储备银行（SARB）发行的电子兰特，是一种央行数字货币（CBDC）
PHP集成方案
基础配置类
<?php
class ZARManager {
private $apiEndpoint;
private $apiKey;
private $environment; // 'sandbox' 或 'production'
public function __construct($environment = 'sandbox') {
$this->environment = $environment;
$this->apiEndpoint = $environment === 'sandbox'
? 'https://sandbox-api.sarb.co.za/v1'
: 'https://api.sarb.co.za/v1';
}
public function convertToDigitalZAR($amount) {
// 转换传统兰特到数字兰特
return [
'amount' => $amount,
'digital_zar' => $this->formatDigitalCurrency($amount),
'conversion_rate' => 1.0, // 1:1 兑换率
'timestamp' => time()
];
}
public function validateDigitalTransaction($transactionId) {
// 验证数字兰特交易
$ch = curl_init($this->apiEndpoint . '/transactions/' . $transactionId);
curl_setopt_array($ch, [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => [
'Authorization: Bearer ' . $this->apiKey,
'Content-Type: application/json'
]
]);
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return [
'success' => $httpCode === 200,
'data' => json_decode($response, true)
];
}
private function formatDigitalCurrency($amount) {
return number_format($amount, 2, '.', '') . ' eZAR';
}
}
钱包管理类
<?php
class DigitalWallet {
private $pdo;
private $zarManager;
public function __construct(PDO $pdo) {
$this->pdo = $pdo;
$this->zarManager = new ZARManager();
}
public function createWallet($userId) {
$walletAddress = $this->generateWalletAddress();
$stmt = $this->pdo->prepare(
"INSERT INTO digital_wallets (user_id, wallet_address, balance_zar, balance_ezar, created_at)
VALUES (?, ?, 0.00, 0.00, NOW())"
);
return $stmt->execute([$userId, $walletAddress]);
}
public function getBalance($userId) {
$stmt = $this->pdo->prepare(
"SELECT balance_zar, balance_ezar FROM digital_wallets WHERE user_id = ?"
);
$stmt->execute([$userId]);
return $stmt->fetch(PDO::FETCH_ASSOC);
}
public function transferToDigital($userId, $amount) {
try {
$this->pdo->beginTransaction();
// 检查传统兰特余额
$balance = $this->getBalance($userId);
if ($balance['balance_zar'] < $amount) {
throw new Exception("余额不足");
}
// 执行转换
$digitalZar = $this->zarManager->convertToDigitalZAR($amount);
// 更新余额
$stmt = $this->pdo->prepare(
"UPDATE digital_wallets
SET balance_zar = balance_zar - ?,
balance_ezar = balance_ezar + ?
WHERE user_id = ?"
);
$stmt->execute([$amount, $amount, $userId]);
// 记录交易
$this->logTransaction($userId, 'ZAR_TO_eZAR', $amount, $digitalZar['digital_zar']);
$this->pdo->commit();
return true;
} catch (Exception $e) {
$this->pdo->rollBack();
throw $e;
}
}
private function generateWalletAddress() {
return 'eZAR_' . bin2hex(random_bytes(16));
}
private function logTransaction($userId, $type, $amount, $digitalAmount) {
$stmt = $this->pdo->prepare(
"INSERT INTO transactions (user_id, transaction_type, amount_zar, amount_ezar, status, created_at)
VALUES (?, ?, ?, ?, 'completed', NOW())"
);
$stmt->execute([$userId, $type, $amount, $digitalAmount]);
}
}
API集成类
<?php
class eZAR_API {
private $clientId;
private $clientSecret;
private $baseUrl;
public function __construct($clientId, $clientSecret) {
$this->clientId = $clientId;
$this->clientSecret = $clientSecret;
$this->baseUrl = 'https://api.ezar.co.za/v2';
}
public function makePayment($fromAddress, $toAddress, $amount, $memo = '') {
$token = $this->getAccessToken();
$payload = [
'from' => $fromAddress,
'to' => $toAddress,
'amount' => $amount,
'currency' => 'eZAR',
'memo' => $memo,
'timestamp' => time(),
'signature' => $this->generateSignature($fromAddress, $toAddress, $amount)
];
$ch = curl_init($this->baseUrl . '/payments');
curl_setopt_array($ch, [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => json_encode($payload),
CURLOPT_HTTPHEADER => [
'Authorization: Bearer ' . $token,
'Content-Type: application/json'
]
]);
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
return [
'success' => $httpCode === 201,
'transaction_id' => json_decode($response, true)['id'] ?? null,
'status' => $httpCode
];
}
private function getAccessToken() {
// OAuth2 认证
$ch = curl_init($this->baseUrl . '/oauth/token');
curl_setopt_array($ch, [
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => http_build_query([
'grant_type' => 'client_credentials',
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret
])
]);
$response = json_decode(curl_exec($ch), true);
curl_close($ch);
return $response['access_token'] ?? null;
}
private function generateSignature($from, $to, $amount) {
// 使用HMAC-SHA256签名
$data = $from . $to . $amount . time();
return hash_hmac('sha256', $data, $this->clientSecret);
}
}
使用示例
<?php
// 初始化
$pdo = new PDO('mysql:host=localhost;dbname=ezar_system', 'user', 'password');
$wallet = new DigitalWallet($pdo);
// 创建钱包
$wallet->createWallet(123);
// 获取余额
$balance = $wallet->getBalance(123);
echo "传统兰特: R" . $balance['balance_zar'] . "\n";
echo "数字兰特: " . $balance['balance_ezar'] . " eZAR\n";
// 转换货币
try {
$wallet->transferToDigital(123, 1000); // 转换R1000到eZAR
echo "转换成功！\n";
} catch (Exception $e) {
echo "转换失败: " . $e->getMessage() . "\n";
}
// API支付
$api = new eZAR_API('your_client_id', 'your_client_secret');
$result = $api->makePayment(
'eZAR_abc123...',
'eZAR_xyz789...',
500.00,
'商品付款'
);
注意事项
- 安全性：使用HTTPS和加密存储敏感数据
- 合规性：遵守南非储备银行(SARB)的监管要求
- 测试环境：先在沙盒环境测试
- 费率：注意交易费用和转换费率
- 备份：定期备份钱包信息和交易记录
这只是一个基础框架,实际生产环境需要更完善的安全措施和错误处理机制。
