you just must have this line in your file:
require("./global.php");

as you can see in globa.php:

PHP Code:

// ###################### Start init #######################

unset($dbservertype);
unset($debug);
//load config
require('./admin/config.php');
if ($debug != 1) {
    unset($showqueries);
    unset($explain);
}

// init db **********************
// load db class
$dbservertype = strtolower($dbservertype);
$dbclassname="./admin/db_$dbservertype.php"; 


all other needed files are included in global.php
