You can use this to sort array based on key.

$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");

ksort($fruits);

and You can also sort the results in query itself.

function get_exam_locations_for_view() {
    $d = $this->db->select('exm_exam_location')->orderBy('exm_exam_location', 'asc')->get();

    if ($d) {
        return $d;
    }
}
