PHPExcel无法保存文件或下载文件。

15
我正在尝试编写一个PHP函数,将一些数据导出到Excel文件。问题在于,如果我将其保存到服务器上,它可以正常运行,但是如果我尝试使用php://output发送到浏览器,它就无法工作。甚至不会显示下载窗口。我已经得到了以下响应:

以下是我的代码:

<?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("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
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;

本周必须完成项目,这个问题让我感到沮丧。 非常感谢任何形式的帮助!

这只是我的代码提示,问题似乎与 Content-Type HTTP 头有关:

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');
}

我尝试更改了类型,但没有成功...我已经查看了stackoverflow中的每一个问题/解决方案,但找不到解决方法。求助! - LuferBRA
前往浏览器设置并查看浏览器对这些 MIME 类型应该执行什么操作,可能已经配置为显示而非启动 Excel? - Axel Amthor
它既不显示也不下载。在Firefox中,我已经设置为保存这种类型的文件... - LuferBRA
嗯,奇怪。错误日志上有任何错误吗(Apache?)Tr<发送任意数据并查看发生了什么:不要使用$objWriter->save('php://output');,而是像这样做echo "hello world"; - Axel Amthor

header(...)函数最常见的问题是输出缓冲区已经被刷新,之后header(...)会导致错误并且无法工作。你有检查过吗? - Axel Amthor

 $writer = IOFactory::createWriter($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();

请在您的回答中添加一些解释,以便其他人可以从中学习。 - Nico Haase

尝试使用这些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 ");

我曾经遇到过同样的问题,看起来下载必须在不同的标签页中打开,而不是在同一个标签页中直接下载。这意味着在初始化下载之前需要重定向到一个新的标签页。

@Vikrant 这是一个含糊的答案,但看起来这是回答问题的尝试。 - Joshua Drake
我更愿意说,这是对问题的评论。 - Vikrant
