php - Global data array in Codeigniter -

-

i have array 

  $meta = array(        'meta_description' => 'lorem ipsum',        'meta_keywords' => 'this, is, a, keyword'   );

if have in controller method, can pass partial so: $this->template->set_partial('header', 'layouts/header', $meta) , passes fine.

i store meta tags in database, i'd ideally put in my_controller , populate array based on database values post's meta tags.

if move outside of controller method, message: undefined variable: meta error.

how can make globally available?

i think figured out.

i created new model handling meta data, insert following my_controller's construct method:

 $meta = $this->meta_data_model->get_item_meta();   $this->template->set_partial('header', 'layouts/header', $meta);

this seems work fine, not sure if there better way of doing it.
