查询生成器中的多个按顺序排序?

I have a Symfony 3 project. And I am sending an array of varying length to a query builder. The query builder looks like this:

function findByQuery($sortBy) {
    return $this->createQueryBuilder('d')
                    ->leftJoin('d.cat', 'dc')
                    ->leftJoin('d.dog', 'dd')
                    ->leftJoin('d.rabbit', 'rr')
                    ->getQuery()
                    ->execute();

}

I want to use the $sortBy parameter to order the results. However the issue is that sometimes the $sortBy (which is an array) will sometimes only contain one element with a key and an order by setting (e.g. ASC or DESC), and other times will contain several keys. In either case I want to be able to sort the results by all the elements. Is there a simple way of doing this?

Many thanks,

    This is as simple as:

    $sortBy = [
        'd.property1'  => 'ASC',
        'd.property2'  => 'DESC'
    ];
    
    function findByQuery(array $sortBy) {
        // create QueryBuilder
        $qb = $this->createQueryBuilder('d')
            ->leftJoin('d.cat', 'dc')
            ->leftJoin('d.dog', 'dd')
            ->leftJoin('d.rabbit', 'rr');
    
        foreach ($sortBy as $property => $dir) {
            $qb->addOrderBy($property, $dir);
        }
    
        return $qb->getQuery()
            ->execute();
    }
