Laravel集合如何从所有项目中删除特定键？
问题描述：
It sounded crazy simple to me at first but I can't find the solution!
Here is My collection :
Collection {#433
#items: array:432 [
0 => array:5 [
"word_id" => 12218
"name" => "ordered"
"rank" => 12217
"is_real" => 1
"id" => 1
]
1 => array:5 [
"word_id" => 12097
"name" => "one-dimensional"
"rank" => 12096
"is_real" => 1
"id" => 2
]
2 => array:5 [
"word_id" => 19679
"name" => "watery"
"rank" => 19678
"is_real" => 1
"id" => 3
]
.
.
.
But I want it to be like this :
Collection {#433
#items: array:432 [
0 => array:5 [
"name" => "ordered"
"id" => 1
]
1 => array:5 [
"name" => "one-dimensional"
"id" => 2
]
2 => array:5 [
"name" => "watery"
"id" => 3
]
.
.
.
How can it be done with laravel collection? Do I have to change my collection to array and do the manipulation myself? How?
起初听起来很简单，但我找不到解决办法！ p>
这是我的收藏： p>
Collection {＃433
#items：array：432 [
0 =＆gt; 数组：5 [
“word_id”=＆gt; 12218
“name”=＆gt; “ordered”
“rank”=＆gt; 12217
“is_real”=＆gt; 1
“id”=＆gt; 1
]
1 =＆gt; 数组：5 [
“word_id”=＆gt; 12097
“name”=＆gt; “one-dimensional”
“rank”=＆gt; 12096
“is_real”=＆gt; 1
“id”=＆gt; 2
]
2 =＆gt; 数组：5 [
“word_id”=＆gt; 19679
“name”=＆gt; “watery”
“rank”=＆gt; 19678
“is_real”=＆gt; 1
“id”=＆gt; 3
]
。
。

但我希望它是这样的： p>
Collection {＃433
#items：array：432 [
0 =＆gt; 数组：5 [
“name”=＆gt; “ordered”
“id”=＆gt; 1
]
1 =＆gt; 数组：5 [
“name”=＆gt; “one-dimensional”
“id”=＆gt; 2
]
2 =＆gt; 数组：5 [
“name”=＆gt; “watery”
“id”=＆gt; 3
]
。
。

如何使用laravel集合完成？ 我是否必须将我的集合更改为数组并自行进行操作？ 怎么样？ p>

答
$collection = $collection->map(function ($item) {
return array_only($item, ['id', 'name']);
});
答
Or you can also use
$collection = $collection->map(function ($item) {
return $item->only(['id', 'name'])
});
