    this is happen because your php has disabled putenv() funtion on your server. To solve it, please remove putenv() from the list of disabled functions in your configuration.

    you can go to "App Store > PHP 8.0 (according to the php version you are using) > Settings > Disabled functions > find putenv() and select delete
    I hope this helps

      apepsiii it's not resolved. it's security issue.

      if (! function_exists('putenv')) {
    function putenv(string $assignment) {}
}

// put that code in app/Common.php

      but i'm trouble when using nginx with .env file, it's never working. in apache it's work.
