这段代码展示了如何用PHP处理包含多个订单价格的数组，分别计算每个订单的最低和最高价格。通过遍历数组，更新每个订单ID对应的最低价和最高价记录，最终得到每个订单的价格范围。

$arr = [
            [
                'order_id' => 1,
                'total_price' => 225.56,
            ],
            [
                'order_id' => 1,
                'total_price' => 456.56,
            ],
            [
                'order_id' => 1,
                'total_price' => 78.56,
            ],

            [
                'order_id' => 2,
                'total_price' => 235.56,
            ],

            $temp[$val['order_id']]['lowprice'] = $val['total_price'] < $temp[$val['order_id']]['lowprice'] ? $val['total_price'] : $temp[$val['order_id']]['lowprice'];
        }

        $minarr = $temp;
