PHP允许你改变你写的,这样就可以迫使一个要下载的文件,通常情况下,浏览器会加载在同一窗口中的文件的HTTP标头。这是完美的文件,如PDF文件,文档文件,图片,视频,您希望您的客户下载,而不是在线阅读。
具体方法如下:

1,你想下载到您的Web服务器上传文件。例如,
huge_document.pdf
2,编辑新的PHP文件 - 我建议将其命名为你下载的文件的名称相同,只是要PHP的扩展。例如:
huge_document.php
3,打开PHP模块:
4,在接下来的一行,设置HTTP头:
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');
?>
9.链接到你的PHP文件的下载链接。例如:
下载巨大的文件(PDF) A>
