After setting up your Laravel Project, you might want to add your custom environment variable.

  • Create or Add Laravel Variable/s located at .env file
  • On the terminal run
$ php artisan config:clear$ php artisan config:cache

If you execute the config:cache command during your deployment process, you should be sure that you are only calling the .env function within your configuration files.

Once the configuration has been cached, the .env file will not be loaded and calls to the env function will return null.

  • Go to your config folder and update app.php.
  • Add your config object
  • Go to your terminal
  • Create a Laravel class by running
php artisan make:controller BlogController
  • On your created controller.
    i.e BlogController.php add the following.

What happened here?

  • We’ve used Config Laravel class
  • Created public $API_SECRETvariable
  • Created __constructor and set $this->API_SECRET to use Config::get('app.api_secret.key').
  • Created class function getAPISecret() to return $this->API_SECRET.
