How to set .env values in laravel programmatically on the fly

Question

Since Laravel uses config files to access and store .env data, you can set this data on the fly with config() method:

config(['database.connections.mysql.host' => '127.0.0.1']);

To get this data use config():

config('database.connections.mysql.host')

To set configuration values at runtime, pass an array to the config helper
