Question

我正在尝试在PHP中编写一个函数来将一些数据导出到Excel文件中。问题是如果我将它保存到服务器它确实工作，但如果我尝试使用php：//输出发送到浏览器它只是不起作用。它甚至没有显示下载窗口。我一直把这些作为回应：

PKaB％A〔CONTENT_TYPES] .XML] K0％F “vRkX׿M + 4℃;'2jgs6，+ VSZ < EM> ATR5 ^ = BB9 + C，9.T“KXR / J，[。`CK6 2 H \ ，ܠ} 3 CC + 9-E | cjBKPN + duO1 o Ba+ G

这是我的代码：

<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);



date_default_timezone_set('Europe/Rome');

require_once 'Classes/PHPExcel.php'; 
/** PHPExcel_IOFactory */
include 'Classes/PHPExcel/IOFactory.php';



$target ='templates/';
$fileType = 'Excel2007';   
$InputFileName = $target.'richiesta.xlsx';   
$OutputFileName = $target     .'Richiesta_'.$_SESSION['User'].'_'.$_SESSION['Last'].'_'.$dat.'.xlsx';



//Read the file (including chart template) 
$objReader = PHPExcel_IOFactory::createReader($fileType); 
//$objReader->setIncludeCharts(TRUE);
$objPHPExcel = $objReader->load($InputFileName); 

 //Change the file 


$objPHPExcel->setActiveSheetIndex(0)
// Add data
            ->setCellValue('C3','10' )
            ->setCellValue('C4','20' )
            ->setCellValue('C5','30')
            ->setCellValue('C5','40' );


$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, $fileType);

//$objWriter->save($OutputFileName);  //This one WORKS FINE!!!

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="Report.xlsx"');


$objWriter->save('php://output'); //NOT WORKING :-(
$objPHPExcel->disconnectWorksheets();
unset($objPHPExcel);

exit;

一旦我必须在本周完成这个项目，我对这个问题感到沮丧。我真的很感激任何帮助！

Answer 1

这只是来自我的代码，作为提示，问题似乎与Content-Typ标题有关：

if (strtolower($type) == 'excel2003') {
    $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="' . $outFileName . '"');
    header('Cache-Control: max-age=0');
} else {
    $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel2007');
    header('Content-Type: application/xlsx');
    header('Content-Disposition: attachment;filename="' . $outFileName . '"');
    header('Cache-Control: max-age=0');
}

Answer 2

我遇到了同样的问题，似乎必须在不同的标签页中打开下载，而不是只在相同的标签页中下载。这意味着您需要在初始化下载之前重定向到新选项卡。

Answer 3

尝试使用以下header（）调用：

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=Report.xlsx");
header("Content-Transfer-Encoding: binary ");

Answer 4

 $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
 $filename = '1111';    
 ob_end_clean(); 
 header("Content-Type: application/vnd.openxmlformats- 
 officedocument.spreadsheetml.sheet");
 header('Content-Disposition:attachment;filename="'.$filename.'.xlsx"');
 header("Cache-Control: max-age=0");
 $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
 $writer->save('php://output');
 exit();

PHPExcel无法保存文件或下载文件
