how can I access environment vars in php

Question

I have set environment variable in /etc/apache2/envvas

export DATABASE='xyz'
export USERNAME='root'
export PASSWORD='pass'

mode_env is also enable.

I tried with

var_dump($_ENV) but the array contain nothing. how can i access it correctly ?

They are the same but getenv will search case insensitive environment vars. — Daan, Mar 27 '15 at 09:57

You can access env variables through this function:

getenv ( string $varname )

So, if for example you want the database name:

$db = getenv('DATABASE');
