php – Remove key when filter collections laravel-ThrowExceptions

Exception or error:

I ran into a problem when using filter with Laravel 5.2, after filtering, I got some unexpected key like “0”, “1”, “2” …, how can I remove it?

Before filter:

[
  {
    "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",

  },

    "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,

    "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,

    "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,

    "updated_at": "2016-06-09 14:28:42",
    "deleted_at": null
  }
]

After filter, id > 5 for example:

{
  "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
  }
}

How can I remove the key 2, 3, and 5 in the result and only get an array like before filtering. Any help is appreciate.
Edit:
My code:

 $result = $result->filter(function ($item) {
                return $item->id > 5;
            })->all();
How to solve:

Try adding values()

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

Answer:

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

Enjoy !!

        $collection = collect([1, 2, 3, 4]);

        $filtered = $collection->filter(function ($item) {
            return $item < 2;
        });

        $filtered->all();
        return $filtered;

result:
[
1
]

But:

    $collection = collect([1, 2, 3, 4]);

    $filtered = $collection->filter(function ($item) {
        return $item > 2;
    });

    $filtered->all();
    return $filtered;

Result: {
“2”: 3,
“3”: 4
}

don’t know how, why…

Answer:

I had have the same problem when sorting:
The example is ordering games result by points and goals. The sorting add key attr in the result. So I use in the final ->values()->all() to get an array values without keys.

Eg:

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

In your case:

$filteredValues = $filtered->values()->all();

I hope it helps you.

Answer:

You can’t do that if you want to use filter() helper, because that’s just how this helper works. I mean there are no parameters or something for this method. You can only rebuild returned collection.

Or, you can use filter() method code to create your own helper, like myFilter() and modify it a bit, for example:

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);
}

Or you could just use collection with indices. I mean usually you’re using collection to iterate over it and these indices won’t disturb you.
