3D City database access

OK so I've got 3D City (stand alone) and i want to get it to get some info from the Dolphin 7 database. how would i get it to get the users Age, Name,  Gender, etc  from the D7 Database?

This is What the Code is now

$city_user = array(
		'user_id' => '638',
		'name' => 'Mike',
		'gender' => '1',
		'age' => '27',
		'country' => 'United States',
		'city' => 'New York',
		'avatar' => $url_abs . 'files/photo.jpg',
	);
