perl作用域函数Eloquent返回STD对象 - Laravel scope function Eloquent returns STD object

Laravel scope function Eloquent returns STD object

我创建了一个Laravel Eloquent scopeFunction，但它返回std对象，即使我使用

toArray()法

是有条件的scopeFunction，第一个条件返回std::对象，第二个

1可以很好地工作并返回数组。有人知道问题出在哪里吗?

function scopeGetList($query, $firstId, $limit, $catid = 'all')
    {
        $cats = NULL;
        if($catid != NULL && $catid != 'all')
        {
            $cats = CategoryList::where("cat_id", "=", $catid)->get()->toArray();
            $res = NULL;
            foreach($cats as $cat)
            {
                $res[] = $query->where("id", "=", $cat['item_id'])->take($limit)->skip($firstId)->orderby("id")->get()->toArray();
            }
            return $res;
        }
        else
        {
            return $query->take($limit)->skip($firstId)->orderby("id")->get()->toArray();
        }
    }

Laravel允许您更改数据库结果的返回方式，即它们的格式。

从api/config/database.php:

"By default, database results will be returned as instances of the PHP
stdClass object; however, you may desire to retrieve records in an
array format for simplicity. Here you can tweak the fetch style."

来自PHP手册:

fetch_style
Controls how the next row will be returned to the caller. This value must be 
one of PDO::FETCH_* constants, defaulting to value of PDO::ATTR_DEFAULT_FETCH_MODE 
(which defaults to PDO::FETCH_BOTH).

请参照:

PDO::FETCH_ASSOC: returns an array indexed by column name as returned in your result set

希望有帮助!
