laravel collection to array
提问by datavoredan
I have two models, Postand Comment; many comments belong to a single post. I'm trying to access all comments associated with a post as an array.
我有两个模型，Post并且Comment；许多评论属于一个帖子。我正在尝试以数组的形式访问与帖子相关的所有评论。
I have the following, which gives a collection.
我有以下内容，提供了一个集合。
$comments_collection = $post->comments()->get()
$comments_collection = $post->comments()->get()
How would I turn this $comments_collectioninto an array? Is there a more direct way of accessing this array through eloquent relationships?
我如何把它$comments_collection变成一个数组？有没有更直接的方式通过雄辩的关系访问这个数组？

You can use toArray()of eloquent as below.
您可以使用eloquent 的toArray()如下。
The toArraymethod converts the collection into a plain PHP array. If the collection's values are Eloquent models, the models will also be converted to arrays
该toArray方法将集合转换为普通的 PHP 数组。如果集合的值是 Eloquent 模型，模型也将被转换为数组
$comments_collection = $post->comments()->get()->toArray()
From Laravel Docs:
来自 Laravel 文档：
toArray also converts all of the collection's nested objects that are an instance of Arrayable to an array. If you want to get the raw underlying array, use the allmethod instead.
toArray 还将作为 Arrayable 实例的所有集合嵌套对象转换为数组。如果要获取原始底层数组，请改用all方法。

Use all()method - it's designed to return items of Collection:
使用all()方法 - 它旨在返回集合项目：
/**
* Get all of the items in the collection.
*
* @return array
*/
public function all()
{
return $this->items;
}

Use collect($comments_collection).
使用collect($comments_collection).
Else, try json_encode($comments_collection)to convert to json.
否则，尝试json_encode($comments_collection)转换为 json。
