Environment Variables
Using the app:install Artisan command you can install the dotenv component:
php <your-app-name> app:install dotenv
The dotenv component allows you to load environment variables from a .env file. And behind
the scenes, it's based on the DotEnv PHP package.
After installing the component, an empty .env.example will be create on the root of your
project, and you should rename it manually to .env.
Assuming that your .env contains:
SECRET_KEY=234567
You can access those variables using the env() helper:
echo env('SECRET_KEY') // outputs 234567
After building your application
After your application is built, you may create a .env file, in the same directory as your build.
