[Duda]Instanciar un objeto de una clase datos

[jh0sz]

Buenas amigos.! Se me presento la siguiente duda, como hago para hacer una consulta por ejemplo de las tallas de esta clase Datos?
Yo mismo cree la clase pero nose como hacer para traer devuelta a los datos... por ejemplo antes de pasar el arreglo multidimensional a clase datos la consulta se hacia de esta forma:

echo $cantidad['nike']['modeloa']['35'];

ahora como seria para traer los datos devuelta?

Código:

<?php
class Datos {
	function getDato(){
   
       return $cantidad = array (
				'nike' => array (
						        'Nikea'=> array (
							                           '35' => 23,
							                           '36' => 36,
							                           '37' => 58,
							                           '38' => 27,
							                           '39' => 12,
							                           '40' => 40
                                                                                 ),
