Access of env-vars in Constants.php

Hi,

i wanted to do something like that in the Config/Constants.php:

PHP Code:

define('IS_LIVE', getenv('CI_ENVIRONMENT') == 'production');
define('IS_DEV', getenv('CI_ENVIRONMENT') == 'development'); 


but i have no access to the env-variables. How could i do that? I want to keep this variables because in my old CI 3 installation i use this constants a lot and migration would be easier.

A second question: Where is the ENVIRONMENT constant defined? I found this term in the documentation. Is this the CI_ENVIRONMENT in the env file?

If you set CI_ENVIRONMENT by .env file, it is not loaded yet when Config/Constants.php is loaded.

The ENVIRONMENT is defined in CodeIgniter::detectEnvironment().
It is not CI_ENVIRONMENT, but when ENVIRONMENT is not defined, CI_ENVIRONMENT value will be set.

Thank you.

Is there an alternative what i can do instead in order to keep these constants? Do i have to create something different and change the constants? (helper, files in Config/Boot Directory). It was nice if you can give me an idea, thanks.

Move the define() to app/Config/Boot/*.php

Move the define() to app/Config/Boot/*.php

Thank you very much. I need to find the right places and implementations for different things :-)
