How to add environment variables to Homestead?

Question

Vagrant

Hi all. The problem is this: I can't get laravel to "see" the environment variable.
I use homestead (vagrant box):

• php7.2.5
  
• vagrant 2.1.2
  
• homestead 6.1.0
  
• laravel 5.6
  

added a variable to composer.json in the config section.
added to .env
added to variable in .bash_profile
added to Homestead.yaml, to variables and to sites.params
Tried to add a variable on the fly with putenv(), none of this worked.
In the stack trace, in the "Environment Variables" section, there is no variable I need.
I do not know where to dig further, please help.

Answer 1

In general, direct editing of $_ENV helped as a temporary solution.
But the .env worked the next day, strange, I did vagrant reload --provision many times.

Answer 2

The variable must be declared for the user that runs the web server that serves Laravel.
In addition, you should pay attention to what is written in the description of the putenv function (about variable names)
