【问题描述】：
有没有办法通过存储在原始域名（example.com/dl.php?id=12）中的 dl.php 文件下载子域（dl1.example.com）中存储的文件
在这种情况下，需要下载的文件位于 dl1（来自不同服务器的子域，并通过在 cpanel 上添加 DNS 记录选项连接）
dl.php 使用 php 标头为客户端创建链接
从 db ($path) 获取的 URL 并用作以下函数的输入：
downloadFile($path,$file_name, 1024, false);
$path 变量包含以下变量：
$path="http://dl1.example.com/Lamp%20with%20phpmyadmin.mp4";
我的主域名上存储的文件没有任何问题，当我想使用子域制作可下载链接时出现问题
我所有的代码：

如何从存储在我的域名上的脚本（我的意思是我的主 Web 服务器主机（例如.com)) ?
如果有任何帮助，我将不胜感激
