我有 tbl_building、tbl_rooms、tbl_lighting 等表。

每个都有自己的元组，因此可以有许多建筑物、建筑物内的许多房间以及房间内的许多照明项目。这是通过为每个建筑物/房间/照明提供自己的 ID 来构建的。

我要完成的任务之一是在 Excel 电子表格中为每个建筑物内的每个房间显示灯光列表。

这是我的代码。这显然是错误的，但我无法理解输出数据。

function getLights($buildingID, $d, $objPHPExcel, $status){

        $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Please Enter Hours Of Usage: ');
        include("setText.php");$status[2]++;

        $groupStart = $status[1].$status[2];
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Lights Used:');
            $status[1]++;
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Count');
            $status[1]++;
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'kWh/yr');
            $status[1]++;
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Energy Saving kWh/yr');
            $status[1]++;
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Saving(£)');
            $status[1]++;
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Cost');
            $status[1]++;
            $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Change To...');    
        $groupEnd = $status[1].$status[2];

        include("setHeadersText.php");groupFill($objPHPExcel, $groupStart, $groupEnd, "calc");
        $status[2]++;$status[1] = chr(65);

        $query = "SELECT r_id FROM tbl_roomDesc WHERE b_id = '$buildingID'";
        $result = $d->query($query);
        $rooms = array();

        array_push($rooms, 2);//echo "<br/>".$row['r_id'];

再花几个小时后问题就解决了（代码中的头部），我已经设法克服了操作我存储在数据库中的数据的困惑。我的问题是我跳入了太多的 for 循环，我应该做加入之前的具体策略。

因此，下面的代码获取建筑物及其房间，并计算建筑物房间内的所有灯光。我希望这对那些遇到数据库问题以及将数据提取/操作为其他格式（如 excel）的人有所帮助。这就是堆栈溢出的正确性。这是代码：

//prints list of lights used in building with kwh/year and savings

函数 getLights($buildingID, $d, $objPHPExcel, $status){

$objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'Lighting Information: ');

$groupEnd = $status[1].$status[2];
