PHPExcel PDF Writer不工作

Question

運行下面的代碼後，我沒有看到任何PDF下載，以及瀏覽器PDF輸出沒有打印。顯示空白頁。

require_once 'Classes/PHPExcel/IOFactory.php'; 
$objPHPExcel = new PHPExcel(); 
$objPHPExcel->getActiveSheet()->setCellValue('c9','40'); 

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF'); 
//You need to include and print to PDF the entire worksheets contained in the workbook 
$objWriter->writeAllSheets(); 

//You need to assign a filename to the PDF file (write.pdf for example) 
header('Content-type:Application/pdf'); 
header('Content-Disposition: attachment;filename="export.pdf"'); 
$objWriter->save('php://output'); 

仍然存在代碼上的一個小錯誤。在瀏覽器中查看PDF時無法下載。請查找附件截圖。

最後上面的代碼中，其解決了這一問題

Answer 1

你正在編寫的PDF到一個文件：

$objWriter->save('write.pdf'); 

這不會輸出任何東西到瀏覽器，或觸發下載。你需要在後面自己丟棄，例如

readfile('write.pdf'); 

或更改保存（）調用

$objWriter->save('php://output'); 

Answer 2

頁眉應該首先創建PDF之前：試試這個：

require_once 'Classes/PHPExcel/IOFactory.php'; 
$objPHPExcel = new PHPExcel(); 
$objPHPExcel->getActiveSheet()->setCellValue('c9','40'); 
//Create the header first before Writing PDF 
header('Content-type:Application/pdf'); 
header('Content-Disposition: attachment;filename="export.pdf"'); 
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF'); 
//You need to include and print to PDF the entire worksheets contained in the workbook 
$objWriter->writeAllSheets(); 
$objWriter->save('php://output');
