Role based result

For example, we have a class:

class A
{
    protected $user;

    public function __construct(GuardContract $user)
    {
        $this->user = $user;
    }

    public function getSomeData()
    {
        $all = [];
        $my  = [...];

        if ($this->user->isModerator()) {
            $all = [...];
        } else if ($this->user->isSuperadmin()) {
            $all = [...];
        }

        return [$all, $my];
    }
}

The getSomeData() method looks ugly and it may be extended to other user roles.
Is there any design pattern to get a result depending on the user role? I am sure that strategy pattern will look legit in this case.
