在PHP中生成下载文件链接

Question

可能重复:
用php打开下载对话框

我的页面中有一个链接说,<a href='test.pdf'>(Test.pdf)</a>.当我点击该链接时,应打开下载对话框以下载该文件.任何人都可以帮助我在PHP中实现这一点吗？

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.

Answer 2

<a href="test.pdf">test.pdf</a>
