How code below work?

dibi::connect([
	'driver'   => 'mysqli',
	'host'     => 'localhost',
	'username' => 'root',
	'password' => '***',
	'database' => 'test',
	'charset'  => 'utf8',
]);

$result = dibi::query('SELECT * FROM users');

How do dibi::query get the connection?

Please do not waste David's valuable time. Do your own research about static classes and properties.
