如何在 PHP 中自动开始下载?

How to Automatically Start a Download in PHP?(如何在 PHP 中自动开始下载?)

问题描述

需要在 PHP 中添加什么代码才能在访问链接时自动让浏览器将文件下载到本地机器?

What code do you need to add in PHP to automatically have the browser download a file to the local machine when a link is visited?

我特别想到了类似于下载站点的功能，一旦您单击软件名称，就会提示用户将文件保存到磁盘?

I am specifically thinking of functionality similar to that of download sites that prompt the user to save a file to disk once you click on the name of the software?

推荐答案

在输出文件前发送以下标题:

Send the following headers before outputting the file:

header("Content-Disposition: attachment; filename="" . basename($File) . """);
header("Content-Type: application/octet-stream");
header("Content-Length: " . filesize($File));
header("Connection: close");

@grom:关于application/octet-stream"MIME 类型很有趣.我不知道，一直只使用应用程序/强制下载":)

@grom: Interesting about the 'application/octet-stream' MIME type. I wasn't aware of that, have always just used 'application/force-download' :)
