PHP将model层调用控制层

将model层中查询数据库，然后在控制层调用读取 用来渲染前端echars，想在model层把x轴、y轴都封装出来
这是model层 想问一下 控制层怎么写

<?php
namespace App\Model\model;
use DB;

class modelData{
public function change($type, $date) {
        switch ($type) {
                case '脱空计':

参考GPT和自己的思路：对于这个问题，控制层应该调用model层的方法来获取封装好的x轴和y轴数据，并将数据传递给前端echars进行渲染。可以在控制层通过以下方式来调用model层的方法：

use App\Model\model\modelData;

class controlData {
 public function getChartData($type, $date) {
  $model = new modelData();
  $chartData = $model->change($type, $date);
  // 将封装好的x轴和y轴数据传递给前端echars进行渲染
 }
}

在上面的代码中，控制层实例化了modelData类，并调用了其change方法来获取封装好的x轴和y轴数据。获取到数据之后，可以将其传递给前端echars进行渲染。

参考Chatgpt 部分内容:1、getData方法接收$type和$date参数
2、然后实例化modelData类，调用change方法获取数据
3、最后将数据传递给视图进行渲染。

change($type, $date); 
return view('view', compact('dataSets')); } } ?>

将view替换为你的视图名称。
