Hey, I'm little confused on "actual environment var's". can you show a little example of symfony how you do this without .env file? :)
Environment variables are set within the OS itself and the application then reads them (via getenv or $_ENV in PHP, I believe). My colleague Dominik wrote a great post about how to set environment variables on different platforms which you might be interested in.
Correct, that is what i meant. The dotenv file (at least in symfony), is used for local development. Once you deploy a symfony project, it wil check if you removed the .env file. If the file still exists, your app will throw an error, thus making it so people HAVE to get rid of it.
