How to Retrieve Environment Variables

All the environment variables are declared in the .env file and we can be accessed environment variables by using env-helper functions (inside app.php).

These environment variables are listed into $_ENV global. We can access these variable as below :

 ‘name’ => env(‘APP_NAME’, ‘Laravel’),

How to Access Configuration Values

For access the configuration values in the application you must use global config helper function.

It returns default values if the configuration values are not initialized.

In case if the configuration values are not initialized, default values are returned.
