laravel 嵌套 foreach 3 层

Question

我正在处理一个 api，我需要 return 数据如下。

{
  "Gamelist": {
    "MarketList": {
      "SelectionList": {}
    }
  }
}

我使用以下方法

        $eventId = 1;
        $sportId = 1;
        $leagueId = 1;

        $events = $this->baseEvents->filterEventsBy($sportId, $eventId, $leagueId);

        //get all the markets for events
        $eventMarkets = $this->baseMarkets->getAllMarketsByEventId($events->pluck('s_base_event_id'));

        //get all the selections for market
        $marketSelections = $this->baseSelections->getAllSelectionsByMarketId($eventMarkets->pluck('s_base_market_id'));

这个项目有这样的关系。一个游戏有很多markets.one 市场有很多选择。我需要按照上面的 json 格式获取这些。我怎样才能做到这一点？我正在使用以下 foreach 结构。

foreach ($events as $event) {
        $markets = $eventMarkets->where('s_base_event_id', $event->s_base_event_id);
        foreach ($markets as $market) {
            $selections = $marketSelections->where('s_base_market_id', $market->s_base_market_id);
            foreach($selections as $selection){

            }
        }
    }

要求的功能

public function filterEventsBy($sportId = null, $eventId = null, $leagueId = null){
        $events = $this->model->join('sports_base_rounds', 'sports_base_rounds.s_base_round_id', '=', 'sports_base_events.s_base_round_id')
            ->join('sports_base_seasons', 'sports_base_rounds.s_base_season_id', '=', 'sports_base_seasons.s_base_season_id')
            ->join('sports_base_leagues', 'sports_base_seasons.s_base_league_id', '=', 'sports_base_leagues.s_base_league_id')
            ->join('sports_base_regions', 'sports_base_regions.s_base_region_id', '=', 'sports_base_leagues.s_base_region_id')
            ->join('sports_base_sports', 'sports_base_sports.s_base_sport_id', '=', 'sports_base_leagues.s_base_sport_id');

        if ($sportId)
            $events->where('sports_base_sports.s_base_sport_id', $sportId);

        if ($leagueId)
            $events->where('sports_base_leagues.s_base_league_id', $leagueId);

        if ($eventId)
            $events->where('s_base_event_id', $eventId);
        else
            $events->where('s_base_event_start_time', '>', Carbon::now());

        return $events->get();
    }



    public function getAllSelectionsByMarketId($marketId){
            $selections = $this->model->whereIn('s_base_market_id', $marketId)
                ->get();

            if(!$selections) return null;

            return $selections;
        }




    public function getAllMarketsByEventId($eventId){
            $markets = $this->model->whereIn('s_base_event_id', $eventId)
                ->get();

            if(!$markets) return null;

            return $markets;

        }

格式化数组数据，试试这个

$data = [];

$eventId = 1;
$sportId = 1;
$leagueId = 1;

$events = $this->baseEvents->filterEventsBy($sportId, $eventId, $leagueId);

//get all the markets for events
$eventMarkets = $this->baseMarkets->getAllMarketsByEventId($events->pluck('s_base_event_id'));

//get all the selections for market
$marketSelections = $this->baseSelections->getAllSelectionsByMarketId($eventMarkets->pluck('s_base_market_id'));

foreach($events as $index => $event){
    forach($eventMarkets as $indx => $market){
        foreach($marketSelections as $section){
            if($section->s_base_market_id == $market->id && $market->s_base_event_id == $event->id){
              $data['GameList'][$index]['MarketList'][$indx]['SelectionList'][] = $section->toArray();
            }
        }
    }
}

$jsonData = json_encode($data);
