Is there a way to combine these two functions? Category System

Combining is easy:

PHP Code:

if( $subject_list = $this->Posts_categories_model->get_list() )
{
    foreach( $subject_list as $sub )
    {
        $data['subject_options'][$sub->id]         = $sub->title;
        $data['subject_name_options'][$sub->title] = $sub->title; 
    }
}
