Laravel env() or config() to get environment variable on command line

You can run Tinker:

php artisan tinker

And then use any of these commands:

env('SESSION_DRIVER')
config('session.driver')

Tinker allows you to interact with your entire Laravel application on the command line, including the Eloquent ORM, jobs, events, and more.

Alternatively, you could create an Artisan command to show you a value from a config file:

php artisan show-config-value session.driver

You can run the artisan command in CMD or terminal, which displays the current environment the application is executing

php artisan env
