如何在 Laravel 中从数据库最小值到最大值获取数据
How get data from database min to max in Laravel
我有一个 table 产品，看起来像这样：
我正在从产品 table 获取数据，但我需要按价格从低到高的数据。我试图通过升序获取产品价格，但我得到的升序是 1、2、3、4 现在我们的价格是 80,900,100,30，我需要这样的 30,80,100,900。我试过这个查询，但没有得到准确的结果。
$low_to_high = DB::table('products')
->where([
['products_categories_id', $id]
])->orderBy('price','ASC')->get();
结果数组：
Array
(
[0] => stdClass Object
(
[id] => 12
[user_id] => 5
[products_categories_id] => 22
[first_cat] => 1
