open download dialog with php

我的页面中有一个链接说，<a href='test.pdf'>(Test.pdf)</a> . 当我单击该链接时，下载对话框应打开以下载该文件。 谁能帮我用 PHP 实现这个？

谢谢

Answer 1

$filename = 'Test.pdf'; // of course find the exact filename....        
header('Pragma: public');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Cache-Control: private', false); // required for certain browsers 
header('Content-Type: application/pdf');

header('Content-Disposition: attachment; filename="'. basename($filename) . '";');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($filename));

readfile($filename);

exit;

将上述文件命名为download.php

HTML:

<a href="download.php">Test.pdf</a>

应该这样做。
