Use PHP while using Django with Nginx in the same block

I have a Django with Nginx configuration which is working fine, here is my configuration:

server {
    listen 80;
    server_name my.hiddendomain.com;

    location / {
        proxy_pass http://127.0.0.1:8000;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }

    location /static/ {
        alias /path/to/your/static/files/;
    }

    location /media/ {
        alias /path/to/your/media/files/;
    }
}

I need to add a custom php script on the same domain however it’s not working. For testing purposes, I’ve created a <?php phpinfo(); file but it’s not working.

In the config file I’ve shown above I’ve added

location /custom-php {
    alias /var/www/html/info.php
}

When I attempt to open the file, the url loads however I get a pop-up asking me where to download the file.

How to resolve this please?
