我有我的Nginx Web服务器设置只是我需要它的工作方式-但现在我需要它在我的服务器的子目录工作-也许更重要的是，在PHP上嵌入在HTML中。
我的服务器都是基于Docker容器的，有一个单独的PHP容器，Nginx和mariadb。
目录结构（容器之外，所有服务的文件都在其中）如下所示.

htdocs
|--Common     (where my CSS, JS, etc is)
|--Resources  (where image and video assets are)
|--labs       (where I experiment)
|  |--ExperimentSite
|--blog       (where I blog)
|--forum      (Forums)
|--family

我试过在根目录下安装.php文件（这个文件可以用），在Wordpress（也可以用）和Vanilla（也可以用）-但是当我试图在/Labs/ExperimentSite中加载.php文件时，它会下载.php文件而不是运行它。另外，我不能运行嵌入在HTML中的.php。
我确信问题一定出在我的site .conf文件上，但即使经过多次实验，我也无法让它正常工作（尽管我已经想出了很多方法来破坏我的网站！）

}

我在这里错过了什么让我的/labs/ExperimentSite工作？我怎样才能让php在html中工作（我试着把location ~ \.php$改为location ~ \.(php|htm|html)$，但这破坏了一切！））
