问题描述
我正在寻找在我的一个网站上的每个视频下方添加下载此文件功能。我需要强制用户下载文件,而不是仅仅链接到它,因为有时会在浏览器中播放文件。问题是,视频文件存储在单独的服务器上。
I'm looking to add a "Download this File" function below every video on one of my sites. I need to force the user to download the file, instead of just linking to it, since that begins playing a file in the browser sometimes. The problem is, the video files are stored on a separate server.
我可以用PHP强制下载吗?
Any way I can force the download in PHP?
推荐答案
你可以尝试这样:
$file_name = 'file.avi';
$file_url = 'http://www.myremoteserver.com/' . $file_name;
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename=\"".$file_name."\"");
readfile($file_url);
exit;
我刚刚测试过,它适用于我。
I just tested it and it works for me.
请注意,对于 readfile
可以读取远程URL,您需要拥有 fopen_wrappers
。
Please note that for readfile
to be able to read a remote url, you need to have your fopen_wrappers
enabled.
