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;
