Question

我正在开发一个允许您传递查询的小类，它将为每个查询创建一个工作表。

仅供参考：这个课程仍处于开发阶段，我将缩减为更小的功能。

我的问题是，由于某些原因，我的表单增量已关闭，我无法确定将其放在何处。

我这样称呼我的班级：

$ex2 = new ExportToExcel2('Somefile');
$ex2->AddSheet('Sheet1', 'Select * from Division;');
$ex2->AddSheet('Sheet2', 'Select * from Zone');
$ex2->ExportMultiSheet();

我应该有两个标签，“Sheet1”和“Sheet2”。这就是我的表格最终看起来的样子。所有数据都在Sheet1和工作表上。

这是我的班级：

class ExportToExcel2 {

    public $AllSheetData = [];
    protected $SheetData = [];
    protected $PHPExcel = '';
    protected $FileName = '';

    function __construct($_filename) {
        $this->FileName = $_filename;
        $this->PHPExcel = new PHPExcel;
    }

    public function AddSheet($_WorkSheetName, $_Query) {
        $this->SheetData['Sheet_Name'] = $_WorkSheetName;
        $this->SheetData['Query'] = $_Query;
        $this->AllSheetData[] = $this->SheetData;
        unset($this->SheetData);
    }

    public function ExportMultiSheet() {

        $Result='';
        $count=0;
        $this->PHPExcel->setActiveSheetIndex(0);
        foreach($this->AllSheetData as $subarray)
        {

            foreach($subarray as $key => $value)
            {

                if($count>0)
                {
                    $this->PHPExcel->createSheet($count);
                    $this->PHPExcel->setActiveSheetIndex($count);
                }

                if($key == 'Query') {

                    $Result = dbQuery($value);

                    //set header row
                    $row = 1; // 1-based index
                    $row_data = sqlsrv_fetch_array($Result, SQLSRV_FETCH_ASSOC);
                    $col = 0;
                    foreach(array_keys($row_data) as $key) {
                        $this->PHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $key);
                        $col++;
                    }

                    //set body rows
                    $row2 = 2;
                    while($row_data = sqlsrv_fetch_array($Result, SQLSRV_FETCH_ASSOC)) {
                        $col2 = 0;

                        foreach($row_data as $key=>$value) {
                            $this->PHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col2, $row2, $value);
                            $col2++;
                        }
                        $row2++;
                    }

                    $count++; 
                }
                if($key =='Sheet_Name')  {
                    $this->PHPExcel->getActiveSheet()->setTitle($value);
                }


                //set all columns to align left
                $this->PHPExcel->getDefaultStyle()->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);

                //show gridlines?
                $this->PHPExcel->getActiveSheet()->setShowGridlines(true);

                //set columns a through z to auto width
                for($col = 'A'; $col !== 'Z'; $col++) {
                    $this->PHPExcel->getActiveSheet()
                        ->getColumnDimension($col)
                        ->setAutoSize(true);
                }
            }

        }


        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="01simple.xls"');
        header('Cache-Control: max-age=0');
        $objWriter = PHPExcel_IOFactory::createWriter($this->PHPExcel, 'Excel2007');
        $objWriter->save('php://output');

        exit;
    }
}

关于在哪里放置$ count ++的任何想法？

您应首先将工作表生成代码从foreach($subarray循环移动到foreach($this->AllSheetData（因为您要为每个.. well ..新工作表添加新工作表。不适用于每个新工作表属性）。

然后，您应该使用与您拥有的代码非常相似的代码，并且$counter将仅在代码的该部分中使用。请注意，要创建新工作表和地点是最后一个，您只需将null传递给createSheet()方法。

所以你的代码应该是这样的：

public function ExportMultiSheet() {

    ...
    $count = 0;
    foreach($this->AllSheetData as $subarray)
    {
      if ($count > 0)
      {
          $this->PHPExcel->createSheet(null);
          $this->PHPExcel->setActiveSheetIndex($count);
      }
      $count++

      foreach($subarray as $key => $value)
      ...
    }
    ...
