Question

我在循环数组时遇到问题，让每个球队在最近10场比赛中得分。这就是我循环遍历这个数组的方式：

       $WarzoneLast10MatchesTeamScore = [];
        foreach($warzoneLast10matches->Results->Teams as $idx => $stats){
            $WarzoneLast10MatchesTeamScore[$idx]['Score'] = $stats->Score;
            $WarzoneLast10MatchesTeamScore[$idx]['Id'] = $stats->Id;
        }

这个问题是它会给我一个错误，因为我试图获得最后10场比赛，所以结果必须是Result [0]，Result [1]，依此类推。这就是我的意思：

+"Results": array:10 [▼
    0 => {#17371 ▼
      +"Links": {#13129 ▶}
      +"Id": {#13130 ▶}
      +"HopperId": "0e39ead4-383b-4452-bbd4-babb7becd82e"
      +"MapId": "c89dae21-f206-11e4-a1c2-24be05e24f7e"
      +"MapVariant": {#13121 ▶}
      +"GameBaseVariantId": "42f97cca-2cb4-497a-a0fd-ceef1ba46bcc"
      +"GameVariant": {#17372 ▶}
      +"MatchDuration": "PT6M50.2813116S"
      +"MatchCompletedDate": {#17367 ▶}
      +"Teams": array:2 [▼
        0 => {#17374 ▼
          +"Id": 0
          +"Score": 1
          +"Rank": 1
        }
        1 => {#17375 ▼
          +"Id": 1
          +"Score": 0
          +"Rank": 2
        }
      ]
      +"Players": array:1 [▶]
      +"IsTeamGame": true
      +"SeasonId": null
      +"MatchCompletedDateFidelity": 1
    }
    1 => {#17378 ▶}
    2 => {#17390 ▶}
    3 => {#17402 ▶}
    4 => {#17414 ▶}
    5 => {#17426 ▶}
    6 => {#17438 ▶}
    7 => {#17450 ▶}
    8 => {#17462 ▶}
    9 => {#17474 ▶}
  ]

我显然不想为每个游戏制作10个循环，然后在我的视图中对每个游戏的分数进行硬编码。如何循环结果对象，然后获取Teams-＆gt;得分和Teams-＆gt; Id对象？

FYI 我知道我可以使用这样的集合：

public function getWarzoneLast10Matches($warzoneLast10matches) {

        // Collect al the results for this array
        $results = collect($warzoneLast10matches->Results);

        $array = $results->map(function($item, $key) {
                return [
                    'Gamertag' => $item->Players[0]->Player->Gamertag,
                    'MapId' => $item->MapId,
                    'GameBaseVariantId' => $item->GameBaseVariantId,
                    'Score' => $item->Teams[0]->Score,
                    'Score2' => $item->Teams[1]->Score,
                    'Id' => $item->Teams[0]->Id,
                    'Id2' => $item->Teams[1]->Id,
                ];
            });


        return $array;
    }

但这不起作用，因为在某些游戏中只有一个团队，如果发生这种情况，那么它会给我一个错误，说明未定义的偏移1，因为没有团队2.我使用的另一种方法顶部不会给我错误。
