PHP dotenv loads environment variables from .env to getenv(), $_ENV and $_SERVER automagically.

You should never store sensitive credentials in your code. Anything that is likely to change between deployment environments – such as database credentials or credentials for 3rd party services – should be extracted from the code into environment variables.

Add your application configuration to a .env file in the root of your project. Make sure the .env file is added to your .gitignore so it is not being checked-in.
