DAO代币合约流动性挖矿系统DAPP开发代码示例

以下是一个简单的 FDF 循环互助智能合约的 PHP 代码示例：

    // 获取当前 FDF 循环互助计划
    public function getCurrentRound() {
        return $this->rounds[count($this->rounds) - 1];
    }

    // 获取 FDF 循环互助总投资额
    public function getTotalInvestment() {
        return $this->totalInvestment;
    }

    // 获取 FDF 循环互助总提现额
    public function getTotalWithdrawal() {
        return $this->totalWithdrawal;
    }
   }
    
// 获取当前 FDF 循环互助计划
$currentRound = $FDFContract->getCurrentRound();
echo "Current Round: " . $currentRound["roundNumber"] . "\n";
echo "Investment Amount: " . $currentRound["investmentAmount"] . "\n";
echo "Investment Rate: " . $currentRound["investmentRate"] . "\n";
echo "Investment Duration: " . $currentRound["investmentDuration"] . "\n";


    // 提现 FDF 循环互助收益
    public function withdraw($roundNumber) {
        $round = $this->getRound($roundNumber);
        $withdrawalAmount = $round["investmentAmount"] * $round["investmentRate"];
        $this->totalWithdrawal += $withdrawalAmount;
        return $withdrawalAmount;
    }

    // 获取指定轮次的 FDF 循环互助计划
    private function getRound($roundNumber) {
        foreach ($this->rounds as $round) {
            if ($round["roundNumber"] == $roundNumber) {
                return $round;
            }
        }
        return null;
    }
}
