Accessing environment variables from php

Question:
How can I access environment variables from php?Answer:
There are two possiblities:- You can use the function getenv() which will work from the CLI as well as via http
- If you're using php via http, then you can use the global array HTTP_ENV_VARS where all environment variables are exported. You need to declare this as a global identifier (see second part of code example).

<?php
function show_home_directory() {
# works from CLI and in web browser:
echo getenv("HOME"). "<br>\n";
# only via http
global $HTTP_ENV_VARS;
echo $HTTP_ENV_VARS["HOME"] . "<br>\n";
}
show_home_directory();
?>
