Php 在筛选集合laravel时删除键

我在使用Laravel 5.2的过滤器时遇到了一个问题，在过滤之后，我得到了一些意外的键，如“0”、“1”、“2”…，如何删除它

过滤前：

[
  {
    "id": 1,
    "user_id": 11,
    "location": "1",
    "content": "1",
    "interest_id": 1,
    "longitude": 1,
    "latitude": 1,
    "place_id": "1",
    "created_at": "2016-06-09 15:44:18",
    "updated_at": "2016-06-02 14:28:42",
    "deleted_at": null
  },
  {
    "id": 2,
    "user_id": 12,
    "location": "Forest Lake QLD, Australia",
    "content": "I'm newbie. Hello everybody",
    "interest_id": 1,
    "longitude": 152.9692508,
    "latitude": -27.6236519,
    "place_id": "ChIJB_NHl8hOkWsRMIne81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  {
    "id": 8,
    "user_id": 11,
    "location": "Hendra QLD, Australia",
    "content": "What time is it?",
    "interest_id": 1,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  {
    "id": 9,
    "user_id": 11,
    "location": "Hendra QLD, Australia",
    "content": "Nice Cream!!!!????????",
    "interest_id": 2,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  {
    "id": 4,
    "user_id": 17,
    "location": "Forest Lake QLD, Úc",
    "content": "Have a nice day!",
    "interest_id": 1,
    "longitude": 152.9692508,
    "latitude": -27.6236519,
    "place_id": "ChIJB_NHl8hOkWsRMIne81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  {
    "id": 7,
    "user_id": 18,
    "location": "Hendra QLD, Australia",
    "content": "Where is Kiet Bui? ❤️❤️❤️❤️❤️",
    "interest_id": 1,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  }
]

过滤器之后，id>5，例如：

{
  "2": {
    "id": 8,
    "user_id": 11,
    "location": "Hendra QLD, Australia",
    "content": "What time is it?",
    "interest_id": 1,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  "3": {
    "id": 9,
    "user_id": 11,
    "location": "Hendra QLD, Australia",
    "content": "Nice Cream!!!!????????",
    "interest_id": 2,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  "5": {
    "id": 7,
    "user_id": 18,
    "location": "Hendra QLD, Australia",
    "content": "Where is Kiet Bui? ❤️❤️❤️❤️❤️",
    "interest_id": 1,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  }
}

public function myFilter(callable $callback)
{
    $return = [];

    foreach ($this->items as $key => $value) {
        if ($callback($value, $key)) {
            // $return[$key] = $value; // original line from filter() method
            $return[] = $value; // Here you want to remove $key
        }
    }

    return new static($return);
}

如何删除结果中的键2、3和5，并仅获得一个与筛选前类似的数组。任何帮助都将不胜感激。 编辑： 我的代码：

如果要使用

filter（）

helper，就不能这样做，因为这正是这个helper的工作方式。我的意思是这个方法没有参数或其他东西。您只能重建返回的集合

或者，您可以使用

filter（）

方法代码创建自己的助手，如

myFilter（）

，并对其进行一些修改，例如：

{
  "2": {
    "id": 8,
    "user_id": 11,
    "location": "Hendra QLD, Australia",
    "content": "What time is it?",
    "interest_id": 1,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  "3": {
    "id": 9,
    "user_id": 11,
    "location": "Hendra QLD, Australia",
    "content": "Nice Cream!!!!????????",
    "interest_id": 2,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  },
  "5": {
    "id": 7,
    "user_id": 18,
    "location": "Hendra QLD, Australia",
    "content": "Where is Kiet Bui? ❤️❤️❤️❤️❤️",
    "interest_id": 1,
    "longitude": 153.0635202,
    "latitude": -27.4225981,
    "place_id": "ChIJAXNg5PBYkWsRIIve81qjAgU",
    "created_at": "2016-06-09 14:28:42",
    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  }
}

public function myFilter(callable $callback)
{
    $return = [];

    foreach ($this->items as $key => $value) {
        if ($callback($value, $key)) {
            // $return[$key] = $value; // original line from filter() method
            $return[] = $value; // Here you want to remove $key
        }
    }

    return new static($return);
}

或者您可以只使用带有索引的集合。我的意思是，通常您使用集合对其进行迭代，这些索引不会打扰您

$result = $result->filter(function ($item) {
                return $item->id < 5;
            })->all();

结果:{ "2": 3, "3": 4 }

不知道如何，为什么…

尝试添加

值（）

我在排序时遇到了同样的问题：
示例是按分数和目标对游戏结果排序。排序将在结果中添加关键字属性。所以我在final->values（）->all（）中使用它来获得一个没有键的数组值

例如：

$sorted=$resultados->sortByDesc（'pts'）->sortByDesc（'gf'）->values（）->all（）；
就你而言：

$filteredValues = $filtered->values()->all();
$filteredValues=$filtered->values（）->all（）；
我希望它能帮助您。
请给我您的代码，您尝试了什么？为什么不尝试
->拒绝（函数（$row）{return$row->id@SafoorSafdar：我试过了，但结果是一样的：（谢谢。也帮了我。我得到了一些稍微不同的东西。我没有使用$collection->values（）->all（），而是使用$collecton->values（）.all（）返回了一个数组，但值返回了一个无键集合如果不使用flant（），它还会删除键
$result = $result->filter(function ($item) {
                return $item->id > 5;
            })->values()->all();

$sorted = $resultados->sortByDesc('pts')->sortByDesc('gf')->values()->all();
$filteredValues = $filtered->values()->all();
