Trying to figure out how to port an Apache SetEnv to NGINX in Centmin

I'm (clearly) not so good with some of the configuration changes needed to move from Apache to NGINX. One of them is where to put a SetEnv setting for a site.

So in Apache, an .htaccess file sets the environment with

Code:

SetEnv CI_ENV development

According to Google, I *think* I can set that with a fastcgi_param, but haven't tested it.

 

How in the heck did that not come up in my Google search?

Hmm, that says I can only put it in main though. I will have multiple environments on the same server. Is the result the same no matter where it's set? If it matters, its obviously running PHP code.
