“SetEnv” via php.ini file

Question

I'm using FuelPHP and the environment information cannot be passed to my command-line script via the framework htaccess file. I read that I can set the same value by modifying my php.ini file. I'm using XAMPP on my localhost, but it doesn't seem to be working -- getenv('FUEL_ENV') returns nothing. I am missing something.

SetEnv FUEL_ENV production
