使用PHP操作数据，将SQLite数据库转换为Excel电子表格

标签： php database excel sqlite data-manipulation

我有tbl_building，tbl_rooms，tbl_lighting等表格。

每个都有他们的元组，因此可以有许多建筑物，建筑物内的许多房间和房间内的许多照明物品。这是通过为每个建筑物/房间/照明提供他们自己的ID来构建的。

我想要实现的任务之一是在excel电子表格中为每个建筑物内的每个房间显示一个灯光列表。

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:";
        /*while($row = $result->fetchArray(SQLITE3_ASSOC)){

问题在花了几个小时后解决（代码中的头），我已经设法克服了操纵我存储在数据库中的数据的困惑。我的问题是我跳进了太多的循环，我应该在进入之前制定具体的策略。

因此，下面的代码占用了建筑物，它的房间，并在建筑物的房间内运行所有灯光。我希望这对那些遇到数据库问题并将数据提取/操作成其他格式（例如excel）的人有用。这就是堆栈溢出的权利。这是代码：

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

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

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