php - 使用 PHP 在服务器上下载多个文件的内容

Question

我有 2 个文件 - 1.csv和2.csv。我可以通过已知方法使用 PHP下载1.csv ：

$file = '1.csv';
header('Content-Description: File Transfer');
header('Content-Type: application/jpeg');
header('Content-Disposition: attachment; filename='.basename($file));
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: public');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
ob_clean();
flush();
readfile($file);

但我的目的是拥有两个文件的下载文件内容 - 1.csv和2.csv。有人对如何实现这一点有一些想法吗？先感谢您。

Answer 1

如果我理解正确，应该这样做。

$file1 = '1.csv';
$file2 = '2.csv';
header('Content-Description: File Transfer');
header('Content-Type: text/comma-separated-values');
header('Content-Disposition: attachment; filename='.basename($file1, '.csv') . '-'  . basename($file2, '.csv') . '.csv');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: public');
header('Pragma: public');
header('Content-Length: ' . (filesize($file1) + filesize($file2)));
ob_clean();
flush();
readfile($file1);
readfile($file2);

考虑对多个文件使用循环，并注意 CSV 文件的 Content-Type 标头的更改。

Answer 2

$file1 = '1.csv';
$file2 = '2.csv';
header('Content-Description: File Transfer');
header('Content-Type: application/jpeg');
header('Content-Disposition: attachment; filename="1-2.csv"');
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: public');
header('Pragma: public');
header('Content-Length: ' . (filesize($file1)+filesize($file2)));
ob_clean();
flush();
echo file_get_contents($file1).file_get_contents($file2);
