PHPExcel多张循环问题

我正在开发一个小类，允许您传递查询，并为每个查询创build一个工作表。

仅供参考：本课程仍在开发中，我将逐步缩减为更小的function。

我的问题是，由于某种原因，我的表增量closures，我不知道在哪里把它。

我打电话给我的class级：

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

我应该有两个选项卡，“Sheet1”和“Sheet2”。 这是我的工作表最终的样子。 所有的数据都在Sheet1和Worksheet上。

这是我的class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; } } 

任何想法放置我的$ count ++的位置？

解决，这是完成的课（直到它没有完成）

 class ExportToExcel2 { public $AllSheetData = []; protected $SheetData = []; protected $PHPExcel = ''; protected $FileName = ''; function __construct($_filename) { $this->FileName = $_filename; $this->PHPExcel = new PHPExcel; //clean the output buffer before download ob_clean(); } public function AddSheet($_WorkSheetName, $_Query) { $this->SheetData['Sheet_Name'] = $_WorkSheetName; $this->SheetData['Query'] = $_Query; $this->AllSheetData[] = $this->SheetData; unset($this->SheetData); } public function ExportMultiSheet($_ExportType='xls') { if(!empty($this->AllSheetData)) { $count=0;$Result=''; $this->PHPExcel->setActiveSheetIndex(0); foreach($this->AllSheetData as $subarray) { if($count>0){ $this->PHPExcel->createSheet(null); $this->PHPExcel->setActiveSheetIndex($count); } $count++; foreach($subarray as $key => $value) { if($key == 'Query') { $Result = dbQuery($value); $this->SetHeaderCells($Result); $this->SetbodyCells($Result); } if($key =='Sheet_Name') { $this->PHPExcel->getActiveSheet()->setTitle($value); } } } $this->ExportType($_ExportType); } } public function ExportSingleSheet($_Query, $_ExportType='xls') { $Result = dbQuery($_Query); $this->SetHeaderCells($Result); $this->SetBodyCells($Result); $this->SetProperties(); $this->ExportType($_ExportType); } private function ExportType($_ExportType) { if($_ExportType=='xls') { $this->DownloadXLS(); } else if($_ExportType=='csv') { $this->DownloadCSV(); } } private function SetProperties() { //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); } //set the first sheet to open first $this->PHPExcel->setActiveSheetIndex(0); } private function DownloadXLS() { $this->SetProperties(); header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Disposition: attachment;filename="'.$this->FileName.'-'.date("ymd").'.xls"'); header('Cache-Control: max-age=0'); $objWriter = PHPExcel_IOFactory::createWriter($this->PHPExcel, 'Excel2007'); $objWriter->save('php://output'); exit; } private function DownloadCSV() { $this->SetProperties(); header('Content-Type: text/csv'); header('Content-Disposition: attachment;filename="'.$this->FileName.'-'.date("ymd").'.csv"'); header('Cache-Control: max-age=0'); $objWriter = new PHPExcel_Writer_CSV($this->PHPExcel); $objWriter->save("php://output"); exit; } private function SetHeaderCells($Result) { $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); $col++; } } private function SetBodyCells($Result) { $row2 = 4; while($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++; } } } 

Answer 1

你应该首先从foreach($subarray foreach($this->AllSheetData循环到你的foreach($this->AllSheetData （因为你想为每个.. well ..新工作表添加新工作表，而不是每个新的工作表属性））的工作表生成代码。

然后你应该使用一个非常类似的代码， $counter只能在代码中使用。 请注意，要创build一个新工作表并将其作为最后一个工作表，您应该简单地将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) ... } ...
