我正在为我的应用程序而苦苦挣扎。我有几个 php 函数导致我出现 503 错误。我正在使用 Nette 框架。

第一个函数通过连接到 Mysql 并将 Mysql 条目与常量相乘来获得“商品生产”的数量。我对此没有任何问题。

public function GetCommodityProduction($estId, $commodity)
    {
        switch ($commodity)
        {
            case 'money':
                $cityCount = $this->database->table('buildings')->where('id = ?', $estId)->fetch()->city;
                $commodityProduction = ($cityCount * self::CITY_PRODUCTION);
                return round($commodityProduction);
            break;
            case 'resources':
                $mineCount = $this->database->table('buildings')->where('id = ?', $estId)->fetch()->mine;
                $commodityProduction = ($mineCount * self::MINE_PRODUCTION);
                return round($commodityProduction);
            break;
            case 'energy':
                ........
        }
    }

第二个函数使用该商品的方式与我获得商品生产的方式相同：

public  function GetCommodityUsage($estId, $commodity)
    {
        switch ($commodity)
        {
            case 'money':
                $barracksCount = $this->database->table('buildings')->where('id = ?', $estId)->fetch()->barracks;
                $tankCount = $this->database->table('army')->where('id = ?', $estId)->fetch()->tank;
                $commodityUsage = (($barracksCount * self::BARRACKS_MONEY_CONSUMPTION) +
                    ($tankCount * self::TANK_MONEY_CONSUMPTION));
                return round($commodityUsage);
            break;
            case 'resources':
                $tankProduction = $this->factoryProduction->getFactoryProduction($estId, 'tank');
                $commodityUsage = (($tankProduction * self::TANK_RESOURCES_CONSUMPTION));
                return round($commodityUsage);
            break;
            case 'energy':
                ..........
        }
    }

当我尝试在这个函数中减去这两个函数的值时，问题就开始了：

public function GetActualCommodityProduction($estId, $commodity)
    {
        switch ($commodity)
        {
            case 'money':
                $actualProduction = $this->GetActualCommodityProduction($estId, 'money') -
                    $this->GetCommodityUsage($estId, 'money');
                return round($actualProduction);
            break;
            case 'resources':
                $actualProduction = $this->GetActualCommodityProduction($estId, 'resources') -
                    $this->GetCommodityUsage($estId, 'resources');
                return round($actualProduction);
            break;
            case 'energy':
                .......
        }
    }

我认为问题在于最后一个功能是服务器超载。但我不确定。您能告诉我如何修改这些功能以使其正常工作吗？
