activerecord - CodeIgniter: Returning data as an object vs array -

there functions return data either object:

$query = $this->db->query("your query");  if ($query->num_rows() > 0) {    foreach ($query->result() $row)    {       echo $row->title;       echo $row->name;       echo $row->body;    } } 

or array:

$query = $this->db->query("your query");  foreach ($query->result_array() $row) {    echo $row['title'];    echo $row['name'];    echo $row['body']; } 

i've returned data arrays, when case returning "object" preferable?

performance. array better object.
