How to retrive/get current environment in Laravel.

The entire variable listed in a (.env) the file will be loaded in the $_ENV PHP when a request is received by an application. However, an ENV helper may be implemented to retrieve the values of the variables in a particular configuration file. If a Laravel configuration file is reviewed, several options can be noticed to assists these helpers in the following way:

‘Debug’=> env ('APP_DEBUG', false?),

The second value that is passed onto the env function is the default value. This value can be used if there is no environment variable present in the given key.
