If you use an anonymous function, it will return the object that are expected.

spl_autoload_register(function ($myclass){
$keyclass = substr($myclass, 0, 1);

switch ($keyclass) {
case 'c':
if (file_exists("class".DIRECTORY_SEPARATOR.$myclass.".php") === true)
require_once ("class".DIRECTORY_SEPARATOR.$myclass.".php");
break;
case 'i':
if (file_exists("interface".DIRECTORY_SEPARATOR.$myclass.".php") === true)
require_once ("interface".DIRECTORY_SEPARATOR.$myclass.".php");
break;
case 'a':
if (file_exists("abstract".DIRECTORY_SEPARATOR.$myclass.".php") === true)
require_once ("abstract".DIRECTORY_SEPARATOR.$myclass.".php");
break;
default:
if (file_exists($myclass.".php") === true)
require_once ($myclass.".php");
}
