Here's a quick tutorial on how to setup Nginx with PHP support. The key? The installation of fastCGI, aka PHP-FPM, so Nginx can serve PHP files to clients.

The PHP engine lets you create dynamic Web pages. PHP also reads HTML, so you can save an HTML file with a PHP extension and upload the new file to your server.

One of simplest ways to accomplish this is to create a PHP program, connect to your Excel file, pull the required data and display the HTML on your Web page.
