我要去拿那个 trophies 由一个团队赢得，每一个奖杯都是在一个特定赛季的比赛中获得的，但是一个团队可以在不同的赛季为同一个比赛赢得一个奖杯。
我写了一个从数据库中提取奖杯的查询：

$sql = $this->db->prepare("SELECT t.*, s.*, c.*,
    t.team_id as team_id,
    s.id as season_id,
    s.name as season_name,
    c.id as competition_id,
    c.name as competition_name
    FROM team_trophies t
    INNER JOIN competition_seasons s ON s.id = t.season_id
    INNER JOIN competition c ON c.id = s.competition_id
    WHERE team_id = :team_id
  ");

基本上我选择了所有 trophies 一个特定的团队 team_trophies 加入了 competition_seasons 对于检索奖杯的赛季细节，对于 competition table。
这很有效，我得到：

[
    {
        "team_id": "23291",
        "season_id": "2",
        "position": "Winner",
        "wins": "4",
        "id": "1093",
        "competition_id": "1093",
        "name": "Premier League",
        "update_at": "2018-06-04 12:12:30",
        "country_id": "1",
        "category": "1",
        "season_name": "2017",
        "competition_name": "Premier League"
    },
    {
        "team_id": "23291",
        "season_id": "3",
        "position": "Runner-up",
        "wins": "1",
        "id": "1093",
        "competition_id": "1093",
        "name": "Premier League",
        "update_at": "2018-06-04 12:14:39",
        "country_id": "1",
        "category": "1",
        "season_name": "2015",
        "competition_name": "Premier League"
    }
]

但我会返回这样一个结果：

[
    {
        "team_id": "23291",
        "position": "Winner",
        "wins": "4",
        "id": "1093",
        "competition_id": "1093",
        "name": "Premier League",
        "update_at": "2018-06-04 12:12:30",
        "country_id": "1",
        "category": "1",
        "seasons": [
                           ["season_name":"2017", "season_id":"2"],
                           ["season_name":"2015", "season_id":"3"],
                       ]
        "competition_name": "Premier League"
    }
]

如您所见，结果中有一行包含 seasons 把奖杯当作 array ，这样可读性更强，避免了冗余。
是否可以使用 sql ? 或者我需要解决问题 php ?
谢谢。
