[SOLVED] How many rows does a query return?

[eluser]WebsiteDuck[/eluser]
Model

Code:

function obtener_todos(){
$query = $this->db->get('Mytable');
        if($query->num_rows>0){
            $data['num_rows'] = $query->num_rows();
            foreach($query->result() as $fila){
                $data['results'][]=$fila;
            }
            return $data;
        }
}

Controller

Code:

function index(){
    $data['main_content'] = 'area_en_nom_vista';

    $filas = $this->area_en_nom_model->obtener_todos();
    $data['num_filas'] = $filas['num_rows'];
    $data['filas'] = $filas['results'];

    $data['title'] = 'Area ensenanza nombrado';
        
    $this->load->view('area_en_nom_vista',$data);
}
