huge_document.php

header('Content-disposition: attachment; filename=huge_document.pdf');
5,然后设置该文件的MIME类型:
header('Content-type: application/pdf');
6,指向你要下载的文件:
readfile('huge_document.pdf');
7,然后关闭PHP块和保存文件:
> [/ BLOCKQUOTE>
8,你的PHP文件应该是这样的:
header('Content-disposition: attachment; filename=huge_document.pdf');
header('Content-type: application/pdf');
readfile('huge_document.pdf');
?>
