Как в PHP реализовать наследование объекта классом как в PHALCON?

class Module {
public function share($moduleName, $func) {
$this->$moduleName = $func();
}
}

$module = new Module();
$module->share('router', function(){
return new Router();
});
$module->share('acl', function(){
return new ACL();
});

class Router {
public function isAllowed() {
$this->acl->isAllowed("user", "Controller");
}
}

class Module
{
    protected $container = [];

    public function share($moduleName, $object)
    {
        $this->container[$moduleName] = $object;
    }

    public function get($moduleName)
    {
        return $this->container[$moduleName];
    }
}

class ACL
{
    public function isAllowed($user, $action) {}
}

class Router
{
    protected $acl;

    public function __construct(ACL $acl)
    {
        $this->acl = $acl;
    }

    public function isAllowed()
    {
        $this->acl->isAllowed("user", "Controller");
    }
}

$module = new Module();
$module->share('acl', new ACL());
$module->share('router', new Router($module->get('acl')));
