LARAVEL:在单个数组中添加键和值

Question

我有一个数据数组,我想在同一个数组中添加一个键和它的值.在这里,addedPost我想添加键favouritePost,它的值是$favouritePost在product键之后.我怎样才能做到这一点 ？

这是我的查询:

$addedPost      =   Post::with(['product','postattribute.attribute.category','user.userDetails'])
                ->whereId($postData['post_id'])
                ->first();
    $favouritePost  = PostFavourite::isAlreadyAdded($postData['post_id'], Auth::id());

    return  [
       'status_code'     =>    $status_code,
       'message'         =>    $message,
       'PostDetails'     =>    $addedPost
    ];

我得到的回应是:

{
"PostDetails": {
    "id": 289,
    "user_id": 12,
    "product_id": 2,
    "demand_or_supply": "Demand",
    "description": "edited1",
    "status": "Expired",
    "created_at": "2018-06-22 07:35:27",
    "updated_at": "2018-07-05 06:42:56",
    "product": {
        "id": 2,
        "title": "Diamond",
        "icon": null,
        "status": "Active"
    } 
}
}

预期结果:

{
"PostDetails": {
    "id": 289,
    "user_id": 12,
    "product_id": 2,
    "demand_or_supply": "Demand",
    "description": "edited1",
    "status": "Expired",
    "created_at": "2018-06-22 07:35:27",
    "updated_at": "2018-07-05 06:42:56",
    "product": {
        "id": 2,
        "title": "Diamond",
        "icon": null,
        "status": "Active"
    },
    "favouritepost": {
         "id": 8,
         "post_id": 289,
         "user_id": 12
    }  
}
}

Answer 1

第一:你$addedPost不是一个阵列,而是一个雄辩的集合.有多种可能性可以做到这一点.最简单的方法是将Array与Collection结合使用.

$union = $addedPost->union($favouritePost->toArray());

对于其他所有解决方案,请查看Laravel文档.这很容易理解.

https://laravel.com/docs/5.6/collections

编辑:虽然我错过了->first()问题的内部只是使用已经提到的解决方案.->first()返回一个StdClassObject,所以你可以像这样处理它:

$addedPost->favouritepost = $favouritePost;

在这种情况下,属性favouritePost被添加到$ addedPost对象.不需要再次调用任何方法.
