主配置文件 (config.php)

<?php
// config.php
return [
    'mmk_to_emmk_rate' => 1, // 1 MMK = 1 eMMK (假设等值)
    'decimal_places' => 2,
    'currency_symbol' => 'Ks',
    'emmk_symbol' => 'eKs',
];

货币基础类 (src/MMK.php)

<?php
// src/MMK.php
namespace App;
class MMK {
    private float $amount;
    private int $decimalPlaces;
    public function __construct(float $amount = 0.0, int $decimalPlaces = 2) {
        $this->decimalPlaces = $decimalPlaces;
        $this->amount = round($amount, $decimalPlaces);
    }
    public function getAmount(): float {
        return $this->amount;
    }
    public function format(bool $includeSymbol = true): string {
        $formatted = number_format($this->amount, $this->decimalPlaces);
        return $includeSymbol ? "Ks {$formatted}" : $formatted;
    }
    public function add(MMK $other): MMK {
        return new MMK($this->amount + $other->amount);
    }
    public function subtract(MMK $other): MMK {
        return new MMK($this->amount - $other->amount);
    }
    public function multiply(float $multiplier): MMK {
        return new MMK($this->amount * $multiplier);
    }
    public function divide(float $divisor): MMK {
        if ($divisor == 0) {
            throw new \InvalidArgumentException("Division by zero");
        }
        return new MMK($this->amount / $divisor);
    }
    public function compareTo(MMK $other): int {
        if ($this->amount > $other->amount) return 1;
        if ($this->amount < $other->amount) return -1;
        return 0;
    }
    public function __toString(): string {
        return $this->format();
    }
}

eMMK类 (src/eMMK.php)

<?php
// src/eMMK.php
namespace App;
class eMMK {
    private float $amount;
    private int $decimalPlaces;
    private string $walletAddress;
    public function __construct(float $amount = 0.0, string $walletAddress = '', int $decimalPlaces = 2) {
        $this->decimalPlaces = $decimalPlaces;
        $this->amount = round($amount, $decimalPlaces);
        $this->walletAddress = $walletAddress;
    }
    public function getAmount(): float {
        return $this->amount;
    }
    public function getWalletAddress(): string {
        return $this->walletAddress;
    }
    public function format(bool $includeSymbol = true): string {
        $formatted = number_format($this->amount, $this->decimalPlaces);
        $walletInfo = $this->walletAddress ? " [{$this->walletAddress}]" : '';
        return $includeSymbol ? "eKs {$formatted}{$walletInfo}" : $formatted;
    }
    public function transfer(eMMK $recipient, float $amount): bool {
        if ($this->amount < $amount) {
            throw new \RuntimeException("Insufficient eMMK balance");
        }
        $this->amount -= $amount;
        $recipient->amount += $amount;
        return true;
    }
    public function verifyTransaction(string $txHash): bool {
        // 模拟交易验证
        return !empty($txHash) && strlen($txHash) > 0;
    }
    public function __toString(): string {
        return $this->format();
    }
}

货币转换器 (src/CurrencyConverter.php)

<?php
// src/CurrencyConverter.php
namespace App;
class CurrencyConverter {
    private float $exchangeRate;
    private int $decimalPlaces;
    public function __construct(float $exchangeRate = 1.0, int $decimalPlaces = 2) {
        $this->exchangeRate = $exchangeRate;
        $this->decimalPlaces = $decimalPlaces;
    }
    public function mmkToEmmk(MMK $mmk): eMMK {
        $convertedAmount = $mmk->getAmount() * $this->exchangeRate;
        return new eMMK(round($convertedAmount, $this->decimalPlaces));
    }
    public function emmkToMmk(eMMK $emmk): MMK {
        if ($this->exchangeRate == 0) {
            throw new \InvalidArgumentException("Exchange rate cannot be zero");
        }
        $convertedAmount = $emmk->getAmount() / $this->exchangeRate;
        return new MMK(round($convertedAmount, $this->decimalPlaces));
    }
    public function batchConvert(array $amounts, string $direction): array {
        $results = [];
        foreach ($amounts as $amount) {
            if ($direction === 'mmk_to_emmk') {
                $mmk = new MMK($amount);
                $results[] = $this->mmkToEmmk($mmk);
            } elseif ($direction === 'emmk_to_mmk') {
                $emmk = new eMMK($amount);
                $results[] = $this->emmkToMmk($emmk);
            }
        }
        return $results;
    }
    public function updateExchangeRate(float $newRate): void {
        if ($newRate <= 0) {
            throw new \InvalidArgumentException("Exchange rate must be positive");
        }
        $this->exchangeRate = $newRate;
    }
}

主入口文件 (index.php)

测试文件 (tests/CurrencyConverterTest.php)

<?php
// tests/CurrencyConverterTest.php
namespace Tests;
use PHPUnit\Framework\TestCase;
use App\MMK;
use App\eMMK;
use App\CurrencyConverter;
class CurrencyConverterTest extends TestCase {
    private CurrencyConverter $converter;
    protected function setUp(): void {
        $this->converter = new CurrencyConverter(1.0); // 1:1 汇率
    }
    public function testMmkToEmmk() {
        $mmk = new MMK(1000);
        $emmk = $this->converter->mmkToEmmk($mmk);
        $this->assertEquals(1000.00, $emmk->getAmount());
    }
    public function testEmmkToMmk() {
        $emmk = new eMMK(500);
        $mmk = $this->converter->emmkToMmk($emmk);
        $this->assertEquals(500.00, $mmk->getAmount());
    }
    public function testInvalidExchangeRate() {
        $this->expectException(\InvalidArgumentException::class);
        new CurrencyConverter(0);
    }
    public function testNegativeAmount() {
        $this->expectException(\InvalidArgumentException::class);
        new MMK(-100);
    }
}

使用方法

  1. 安装: 将文件复制到您的PHP项目目录
  2. 运行: 通过浏览器访问 index.php
  3. 测试: 使用 phpunit tests/CurrencyConverterTest.php 运行测试

主要功能

  • ✅ 支持MMK和eMMK的基本运算（加、减、乘、除）
  • ✅ 货币格式化和比较
  • ✅ eMMK钱包地址管理
  • ✅ 货币转换（MMK ↔ eMMK）
  • ✅ 批量转换功能
  • ✅ 错误处理和验证

这个项目提供了一个完整的缅甸货币处理系统,可以根据实际需求进一步扩展功能。
