SIMULATION -
Consider the following code. Which keyword should be used in the line marked with "KEYWORD" instead of "self" to make this code work as intended? abstract class Base { protected function __construct() {
}
public static function create() {
return new self(); // KEYWORD
}
abstract function action();
}
class Item extends Base {
public function action() { echo __CLASS__; }
}
$item = Item::create();
$item->action(); // outputs "Item"
