 All of the variables listed in the `.env` file will be loaded into the `$_ENV` PHP super-global when your application receives a request. However, you may use the `env` function to retrieve values from these variables in your configuration files. In fact, if you review the Laravel configuration files, you will notice many of the options are already using this function:
 
 ```php
-'debug' => env('APP_DEBUG', false),
+'debug' => (bool) env('APP_DEBUG', false),
 ```
 
 The second value passed to the `env` function is the "default value". This value will be returned if no environment variable exists for the given key.
