Helper to retrieve values from enviroment variables

[samdark]

Is it better than any existing dotenv libraries?

[leandrogehlen]

The problem is get the value from environment variables.
These libraries just load the environmnet variables from file

[samdark]

Nope. These usually do both i.e. environment variables + files with files priority.

I guess that https://github.com/vlucas/phpdotenv is the most popular and used in laravel.
And i didn't find this feature.

Laravel has implemented the same feature
https://github.com/laravel/framework/blob/5.6/src/Illuminate/Support/helpers.php#L604

I don't see pros of having it then.

1. Default value is easy to achieve: getenv('TEST') ?: 'default'.
2. Stripping quotes and converting string values is weird. For example, you may want to pass string value empty and won't be able to.

[leandrogehlen]

You are right.
