#codeigniter database object syntax

Something that I feel is useful throughout CodeIgniter is the different between array syntax such as

$data['title']

in order to later pass it into a view

$this->load->view('viewname',$data);

and object syntax for things like activerecords with the database class such as

$query = $this->db->get('tablename')->result();

and then if your table had a field of

'name'

you'd reference it like

echo $query->name;
