无法从第二个服务器目录加载 PHP 文件

Question

我的服务器有一个根目录，/home/forge/example.com/current/ionic/www以及一个辅助 API PHP 目录，位于/home/forge/example.com/current/public。

当用户浏览 example.com/api 时，网站应该从那里加载/home/forge/example.com/current/public（与根目录不同）。

我已经能够使用alias并加载成功配置它index.html，但是 php 文件无法加载。

我在 StackExchange 上发现，这是由于Nginx 长期存在的错误。

我读过几篇帖子，其中的解决方法是重写 URL。

如何使用 Nginx 别名从其他目录加载 PHP？

我怎样才能避免使用 nginx 中的别名？

这是我的站点可用文件。
