使用 PHP 处理数据，将 SQLite 数据库转换为 excel 电子表格 [关闭]

【问题标题】：Using PHP to manipulate data, transforming an SQLite database to an excel spreadsheet [closed]使用 PHP 处理数据，将 SQLite 数据库转换为 excel 电子表格 [关闭]

【问题描述】：

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 电子表格中显示每个建筑物内每个房间的灯光列表。

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'];



            //echo "<br/>Building:";

【问题讨论】：

  • 我在 for 循环/while 循环中的某个地方搞砸了，只是想要一种更简单的方法来做到这一点。大量的数据操作开始让我的大脑一片混乱。而且..由于数据太多，我尝试了少量数据。这就是我现在正在尝试的。
  • 抱歉，我们不会通读代码墙来寻找“显而易见”的位。
  • 谢谢，只是想获得帮助，请随时编辑！
  • 将代码逻辑分解为可管理的部分，然后依次查看每个部分，直到发现逻辑与预期不符的地方——标准调试实践
  • 看下面的代码，现在可以了，看完代码后，只需要多花点时间就可以了。

【解决方案1】：

在花费了几个小时后问题得到解决（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，我在加入之前应该制定一个具体的策略。

因此，下面的代码获取了建筑物及其房间，并计算了建筑物房间内所有灯光的总和。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：

    $status[1]++;
    $objPHPExcel->getActiveSheet()->setCellValue($status[1].$status[2], 'kWh/yr');

    $objPHPExcel->getActiveSheet()->setCellValue($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');

还有来自 php 手册的旧信任数组：
