Question

我正在尝试使用PHPExcel下载我的excel文件，它会下载一个文件..但它是空的..！基本上我试图修改01simple.php示例（当文件保存到服务器时工作正常）下载文件。但它是一个空文件。我读了几个例子和主题，但我仍然有点困惑。这是我的代码。谢谢

<?php

/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');
/*
if (PHP_SAPI == 'cli')
die('This example should only be run from a Web Browser');*/

/** Include PHPExcel */
require_once dirname(__FILE__) . '/PHPExcel/Classes/PHPExcel.php';


// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Set document properties
$objPHPExcel->getProperties()->setCreator("at")
                         ->setLastModifiedBy("At")
                         ->setTitle("title")
                         ->setSubject("Libro ")
                         ->setDescription("Libro")
                         ->setKeywords("excel openxml php")
                         ->setCategory("At");


// Add some data
$objPHPExcel->setActiveSheetIndex(0)
        ->setCellValue('A1', 'Hello')
        ->setCellValue('B2', 'world!')
        ->setCellValue('C1', 'Hello')
        ->setCellValue('D2', 'world!');

// Miscellaneous glyphs, UTF-8
$objPHPExcel->setActiveSheetIndex(0)
        ->setCellValue('A4', 'Miscellaneous glyphs')
        ->setCellValue('A5', 'éàèùâêîôûëïüÿäöüç');

// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Libro Soci aa. 2015');


// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);


// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="Libro Soci 2015.xlsx"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');

// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');
exit;

通过在工作表末尾添加ob_end_clean来解决，只需输出

PHPExcel将下载空文件
