PHP 创建一个 excel 文件并通过一个函数 return 它

PHP create an excel file and return it via a function

我正在研究 yii2。我正在通过 php spreadsheet 创建一个 excel 文件。现在,我正在浏览器中下载它。现在,我想 return 文件而不下载它。

代码:

// Created 2 worksheet in one excel file successfully 

$filename = 'Meter Breakdown List '.date('d-m-y').'.xlsx'; //save our workbook as this file name
    // Redirect output to a client’s web browser (Xlsx)
    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
    header('Content-Disposition: attachment;filename="'.$filename.'"');
    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');

    $writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');

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

之后我想要它 return 像 return $filename;

这样的文件

然后将 returned 文件传递​​给名为 sendEmail($filename)

的函数

在这个功能中,我已经设置了通过附件发送电子邮件的过程。

如何在不下载文件的情况下发送文件?

注:

我也看了问题:PHP create Excel spreadsheet and then email it as an attachment

样本code保存文件

<?php

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Hello World !');

$writer = new Xlsx($spreadsheet);
$writer->save('hello world.xlsx');

文件保存后,您可以将文件发送到邮箱

sendEmail('hello world.xlsx');

完成所有操作后,您可以删除保存的文件

unlink('hello world.xlsx');
