PHPExcel 编写器 returns 空文件

Question

我目前正在使用 PHPExcel 编写数据导出并不断得到一个空文件。我制作了一个测试脚本，它应该给我一个 excel 文件，其中填充了 3 个测试单元格，但它也给我一个空的 excel 文件。

当我 print_r $objphpexcel 它仍然显示单元格已填充。但是当我 print_r 作者时，它只有 header 数据可用而没有单元格内容..

<?php
include_once 'models/PHPExcel.php';
include_once 'models/PHPExcel/IOFactory.php';
$objPHPExcel = new PHPExcel();
// Set document properties
$objPHPExcel->getProperties()->setCreator('Company')
    ->setLastModifiedBy('User')
    ->setTitle('Sample_title');



// Add header (first row) data
$objPHPExcel->setActiveSheetIndex(0)
    ->setCellValue('A1', 'EXCEL EXPORT')
    ->setCellValue('B1', 'TEST')
    ->setCellValue('C1', 'CEL');



$next_excelrow=2;

//ITERATION TROUGH DATA HERE

// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('A');
// Set active sheet index to the first sheet, so Excel opens this as the     first sheet
$objPHPExcel->setActiveSheetIndex(0);
//echo'<pre>'.print_r($objPHPExcel,true).'</pre>';exit; <-- this print_r still has the data
// Redirect output to a client’s web browser (Excel5)
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="sample_export.xls"');
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
//header('Content-Type: text/html; charset=UTF-8');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');




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

如您所见，我已经将它缩小到一个简单的导出，但我下载的仍然是一个空的损坏文件..

有人可以帮忙吗？谢谢！

Answer 1

尝试改变$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); 至 $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');

Answer 2

由于 PHPExcel 已被弃用，我将转向 PHPSpreadsheet

Answer 3

                header('Content-Type: application/vnd.ms-excel');
                header('Content-Disposition: attachment;filename="file.xlsx"');
                header('Cache-Control: max-age=0');
                header('Cache-Control: max-age=1');

                header ('Expires: '.gmdate('D, d M Y H:i:s').' GMT');
                header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT');
                header ('Cache-Control: cache, must-revalidate');
                header ('Pragma: public');

                $objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
                $objWriter->save('file.xlsx');

尝试像示例一样将其保存到文件中，而不是 php://输出。适合我。
