env()If you execute theconfig:cachecommand during your deployment process, you should be sure that you are only calling theenvfunction from within your configuration files. Once the configuration has been cached, the.envfile will not be loaded and all calls to theenvfunction will returnnull.
'name' => env('APP_NAME', 'Laravel'),config('app.name') где-нибудь в коде, чтобы получить данные из этой настройки. Вот только если вы вызовите env('APP_NAME') вы, возможно, получите ошибку, в случае, если эта переменная не задана в переменных среды.'endpoint' => 'https://' . env('API_DOMAIN') . '/some/subroute',
