合并Laravel个采集结果，聚合一个字段

Question

我有一个包含重复结果的集合，但在相关字段中有不同的数据。我想消除重复项，但通过组合该字段的值来保留其他数据。我似乎找不到一个好的方法来做到这一点。我的结果集如下所示：

"bankers" => Collection {#663 ▼
  #items: array:5 [▼
    0 => Collection {#465 ▼
      #items: array:5 [▼
        "banker_id" => 13
        "banker_name" => "John Banker"
        "type" => "lending"
        "deal_score" => 1
      ]
    }
    1 => Collection {#455 ▼
      #items: array:5 [▼
        "banker_id" => 62667
        "banker_name" => "Harvey Aandreau"
        "type" => "lending"
        "deal_score" => 0
      ]
    }
    2 => Collection {#419 ▼
      #items: array:6 [▼
        "banker_id" => 13
        "banker_name" => "John Banker"
        "type" => "quotes"
        "deal_score" => 1
      ]
    }
    3 => Collection {#410 ▼
      #items: array:6 [▼
        "banker_id" => 297
        "banker_name" => "Melissa Jablonsky"
        "type" => "quotes"
        "deal_score" => 1
      ]
    }
  ]
}

我想删除第二个重复项 "John Banker"，但将 "type" 字段的值添加到上一条记录，如：

"bankers" => Collection {#663 ▼
  #items: array:5 [▼
    0 => Collection {#465 ▼
      #items: array:5 [▼
        "banker_id" => 13
        "banker_name" => "John Banker"
        "type" => "lending, quotes"
        "deal_score" => 1
      ]
    }
    1 => Collection {#455 ▼
      #items: array:5 [▼
        "banker_id" => 62667
        "banker_name" => "Harvey Aandreau"
        "type" => "lending"
        "deal_score" => 0
      ]
    }
    3 => Collection {#410 ▼
      #items: array:6 [▼
        "banker_id" => 297
        "banker_name" => "Melissa Jablonsky"
        "type" => "quotes"
        "deal_score" => 1
      ]
    }
  ]
}

我需要保留当前订单。 "type" 字段可以根据需要更改为数组。如有任何建议，我们将不胜感激。

感谢 Joseph Silber 提出以下建议：

$bankers->groupBy('banker_name')->map(function ($bankers) {
    return array_merge($banker[0]->all(), [
        'type' => $bankers->pluck('type')->implode(',');
    ]);
});
