如何使用PhpSpreadSheet將Xlsx文件下載到客戶端

Question

我正在嘗試使用 PhpSpreadSheet 下載“Xlsx”文件，我確信代碼工作正常，但我得到的只是這些奇怪的字符出現在我的控制台中

我在 stackoverflow 中嘗試了幾乎所有的解決方案，但都在下面的圖片中給出了相同的結果

我的代碼

<?php


require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet(); 


$sheet->setCellValue('A1', 'ID'); 
$sheet->setCellValue('B1', 'Name'); 
$sheet->setCellValue('C1', 'Name2'); 
$sheet->setCellValue('D1', 'Name3');
 $sheet->setCellValue('E1', 'Type'); 

// Write an .xlsx file  
$date = date('d-m-y-'.substr((string)microtime(), 1, 8));
$date = str_replace(".", "", $date);
$filename = "export_".$date.".xlsx";

try {
$writer = new Xlsx($spreadsheet);
    $writer->save($filename);
    $content = file_get_contents($filename);
} catch(Exception $e) {
    exit($e->getMessage());
}

header("Content-Disposition: attachment; filename=".$filename);

unlink($filename);

Answer 1

您將電子表格保存到一個文件中，然后讀取該文件，但您沒有將文件發送到瀏覽器，您發送的只是帶有文件名的標題（這只是一個建議，將出現在文件保存日志中）

try {
    $writer = new Xlsx($spreadsheet);
    $writer->save($filename);
    $content = file_get_contents($filename);
} catch(Exception $e) {
    exit($e->getMessage());
}

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment; filename="' . urlencode($filename) .'"' );

echo $content;  // this actually send the file content to the browser

unlink($filename);

我剛剛運行了這個確切的代碼，它運行良好，使用 Chrome 和 Firefox 和 Edge 瀏覽器。

<?php

require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet(); 


$sheet->setCellValue('A1', 'ID'); 
$sheet->setCellValue('B1', 'Name'); 
$sheet->setCellValue('C1', 'Name2'); 
$sheet->setCellValue('D1', 'Name3');
$sheet->setCellValue('E1', 'Type'); 

// Write an .xlsx file  
$date = date('d-m-y-'.substr((string)microtime(), 1, 8));
$date = str_replace(".", "", $date);
$filename = "data/export_".$date.".xlsx";

try {
    $writer = new Xlsx($spreadsheet);
    $writer->save($filename);
    $content = file_get_contents($filename);
} catch(Exception $e) {
    exit($e->getMessage());
}

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment; filename="' . urlencode($filename) .'"' );

echo $content;  // this actually send the file content to the browser

unlink($filename);

以下似乎有效：

注意：$filePath 應該是具有正確權限的文件夾

<?php 

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet(); 


$sheet->setCellValue('A1', 'ID'); 
$sheet->setCellValue('B1', 'Name'); 
$sheet->setCellValue('C1', 'Name2'); 
$sheet->setCellValue('D1', 'Name3');
$sheet->setCellValue('E1', 'Type'); 

// Write an .xlsx file  
$date = date('d-m-y-'.substr((string)microtime(), 1, 8));
$date = str_replace(".", "", $date);
$filename = "export_".$date.".xlsx";
$filePath = __DIR__ . DIRECTORY_SEPARATOR . $filename; //make sure you set the right permissions and change this to the path you want

try {
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xls');
$writer->save($filePath);
} catch(Exception $e) {
    exit($e->getMessage());
}

// redirect output to client browser
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="'.$filename.'"');
header('Cache-Control: max-age=0');

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

Answer 3

嘗試將此用於您的 header 'Content-Type' -

header('Content-Type: application/vnd.ms-excel; charset=UTF-8');
