You can use the collection like an array:
您可以像使用数组一样使用集合：
$cats[5] = 'BMW';

I have played with it, and it doesn't look good, but here is something which might help you.
我玩过它，它看起来不太好，但这里有一些可能对你有帮助的东西。
$item = (object) ['id' => 5, 'val' => 'cat']
{#925 +"id": 5, +"val": "cat"}
collect([$item])
{#924 all: [ {#925 +"id": 5, +"val": "cat"}]}
collect([$item])->keyBy('id')->transform(
function($obj){ return $obj->val;
})
{#907 all: [5 => "cat"]}
So I think using keyBy()and transform()might get you where you're wanting to go.
所以我认为使用keyBy()并且transform()可能会让你到达你想去的地方。
