Answer 1

Look at the log. I once made a mistake that also caused PHP not to be parsed, and the PHP file was directly returned and downloaded. The reason at that time was that I commented PHP forwarding, and then the browser request formed a cache. When I modified the correct configuration and restarted the server, the server was not requested at all due to caching reasons. So it is recommended that you restart nginx first, clear the browser cache, and then look at the error.log and access.log.

Answer 2

nginx does not support PHP parsing:

The nginx.conf configuration file under Baidu supports PHP

location ~ .php$ {

           root /usr/local/nginx/html; #指定php的根目录
           fastcgi_pass 127.0.0.1:9000;#php-fpm的默认端口是9000
           fastcgi_index index.php;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           include fastcgi_params;
    }
