Question

我已经创建了一个Laravel Eloquent scopeFunction但它返回了std对象，即使我使用

toArray()方法。

这是一个条件scopeFunction，第一个条件返回std::个对象，而第二个

一个很好用并返回数组。任何人都可以看到问题是什么？

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，即格式。

来自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 manual：

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).

在您的情况下，请参阅：

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