我有一个像这样的餐桌产品：

enter image description here

我正在从产品表中获取数据，但我需要按价格从低到高的数据。我试图通过升序获得产品价格，但我正在按1,2,3,4升序获得商品现在，我们有80,900,100,30的价格，我需要像这样的30,80,100,900。我已经尝试过该查询，但是没有得到确切的结果。

$low_to_high = DB::table('products')
                   ->where([
                            ['products_categories_id', $id]
                          ])->orderBy('price','ASC')->get();

结果数组：

您可以通过添加零这样的东西来实现

SELECT * FROM SampleData ORDER BY data_char+0;

您还可以更改数据库中的数据类型以获得准确的结果。
