I find it annoying to manually export the Laravel
.env file to Nginx, so I've created a simple exporter, which can be found at https://github.com/RamyTalal/Exporter. The exporter currently supports Nginx, Apache, IIS, and lighttpd.
$ php artisan env:export nginx --file=.env
fastcgi_param key1 "value1"; fastcgi_param key2 "value2";
