Question

在一个查询中选择两个实体（使用连接）时，Doctrine返回一个扁平数组，其中每个实体都选择了一个元素。我想要每行一个数组元素，在该元素内部它包含在该行中选择的实体数组。

$qb = $this->_em->createQueryBuilder();

$qb
    ->select('competition')
    ->addSelect('competitor')
    ->from('Entity\Competition', 'competition')
    ->leftJoin('Entity\Competitor', 'competitor', \Doctrine\ORM\Query\Expr\Join::WITH, 'competition = competitor.competition')
    ->leftJoin('Entity\Athlete', 'a', \Doctrine\ORM\Query\Expr\Join::WITH, 'competitor.athlete = a')
    ->andWhere('co IS NULL')
    ->orWhere('co.athlete = :athleteId')
    ->setParameter('athleteId', $athleteId)

$data = $qb->getQuery()->getResult();

exit(var_dump($data));

此查询返回一个包含四个元素的数组：

[0] = Competition
[1] = Competitor
[2] = Competition
[3] = null

它返回的数据是正确的，但我希望它采用以下格式：

[0] = [
    [competition] = Entity\Competition
    [competitor] = Entity\Competitor
]
[1] = [
    [competition] = Entity\Competition
    [competitor] = null
]

我如何让Doctrine这样做？
