Environment

Laravel use dotenv to load env variables. By default the dotenv will use “.env” file.

Any variable in your .env file can be overridden by external environment variables such as server-level or system-level environment variables.

Laravel will attempt to load .env.[APP_ENV] file if existed, if not the default is .env file.
