To connect to mysql you do something like this:
<?php
$db = DB::Connect();
?>
This uses the public static DB class variables $host, $user, $pass, $host and $dbas. Additionally
you can also set $dbug to turn on the debug window. For example:
<?php
DB::$user = 'root';
DB::$pass = '';
DB::$host = 'localhost;
DB::$dbas = 'mysql';
DB::$dbug = true;
$db = DB::Connect();
?>
