Dotenv does not overwrite values set in PHP-FPM via nginx fastcgi_param

[mpavey0]

I am running a development server using PHP 7.1, PHP-FPM, nginx 1.8.0, and Dotenv 2.4.0. The nginx .conf file for my server, I eventually figured out, included a fastcgi_param directive setting the APP_ENV environment variable to dev. Consequently, even though I had a line APP_ENV=development in my .env file, which was being loaded by Dotenv, a call to getenv('APP_ENV') returned dev and not, as expected, development.

As I understand the Dotenv documentation, this is dependent on using overload() and not simply load(). However, the two behaved similarly.

This seems very similar to issue #39. Ideally it would be great to change the behavior of Dotenv (assuming this is possible). In the meantime, it would at least be helpful to note the limitation in the documentation (in the section about overwriting values).

Fixed by #284 I think?
