New DB connection on custom page

[Polite]

Hello,

I have created a custom page (server-stats.php), the page works fine however I was wondering what's the best to open a new DB connection?

Thanks,

you can include global.php file by using require_once function & MyBB's database can be queried through it ..

<?php
define('IN_MYBB', 1);
require_once "global.php";
// MyBB database can be accessed ...

I am already including global.php file (require_once) but im not looking to query anything inside of myBBs database I want to connect to a new different database
