好的，请先提供数据的示例给我。并且告诉我怎么计算折扣后的单价

我的数据格式是这样的。


{
  "bill_source": "ISV",
  "bill_date": "2024-03-02",
  "customer_id": "1518003654899018752",
  "remark": "德康堂  效期-来自营销云-XJTHRK00004899670",
  "custom_field": {
    "custom_field__1__28jianb2nq7c6u": "德康堂  效期"
  },
  "material_entity": [
    {
      "material_id": "1332553783003063296",
      "stock_id": "1277526505122993152",
      "qty": 1,
      "tax_price": 86,
      "discount2": "0.38",
      "unit_id": "1269832546082910208",
      "batch_no": "20220701D",
      "comment": "德康堂  效期",
      "kf_date": "2022-07-12",
      "valid_date": "2024-07-11",
      "kf_period": "730",
      "kf_type": "1"
    }
  ]
}

我的规则是下面的:先将税费:tax_price与折扣率:discount2的值相乘，然后取整保留2位小数点，然后赋值给tax_price，最后删除折扣率

我已经帮你写好了这个加工厂，将该加工厂代码新增到方案的事件 AfterTargetGenerate 即可。

<?php
/**
 * AfterTargetGenerate class
 * 目标队列生成后加工厂
 */
class AfterTargetGenerate
{
    /**
     * params variable
     * 目标队列生成的请求参数内容
     * &值引用
     * @var array
     */
    protected $params = [];

    /**
     * ids variable
     * 目标队列所关联的原始数据 ids (mongodb objectId)
     * @var array
     */
    protected $ids = [];

    public function __construct(&$params, $ids)
    {
        $this->params = &$params;
        $this->ids = $ids;
    }

    public function run()
    {
        foreach ($this->params['material_entity'] as &$item) {
            $item['tax_price'] = round($item['tax_price']*$item['discount2'],2);
          	unset($item['discount2']);
        }
    }
}
