  8. Je recommande plutôt ce code qui utilise la fonction count du queryBuilder.

    $queryBuilder = $this->createQueryBuilder(‘f’);
    $queryBuilder->select($queryBuilder->expr()->count(‘f’));
    $queryBuilder->where(‘f.user = :user’)->setParameter(‘user’, $user);

    $query = $queryBuilder->getQuery();
    $singleScalar = $query->getSingleScalarResult();
    return $singleScalar;
