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);

require_once 'Classes/PHPExcel.php';

$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

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

$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!
$objWriter->save('php://output');
,而是像这样做echo "hello world";

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
