apache_getenv() not found with cli debugging

Hi,

First, I'm new in PhpStorm debugging.

I try to debug a simple PHP script using PHPStorm debugger with console only (no browser).

It seems to work (I can step over some lines), but crashes when it reach apache_getenv() call.

require_once apache_getenv("PATH_ROOT") . "config/config.php";

Console: 

PHP Fatal error: Uncaught Error: Call to undefined function apache_getenv() in D:\git\xxxx
Fatal error: Uncaught Error: Call to undefined function apache_getenv() in D:\git\xxxx
Stack trace:

#0 {main}
Error: Call to undefined function apache_getenv() in D:\git\xxxx
 thrown in D:\git\xxxx

In this case, the function is used to get project path.
How could I tell PhpStorm to use correctly this function ? I already searched on Internet but found nothing relevant.
