老师批语：
自撸框架继承第三方库, 使用第三方类的成员为自己项目增砖添瓦:
Model ———————————
<?php//框架核心 模型类namespace core;use Medoo\Medoo;class Model extends Medoo{public function __construct(){$options = ['database_type' => 'mysql','database_name' => 'study','server' => 'localhost','username' => 'root','password' => '123456'];// 继承父类构造方法parent::__construct($options);}}
View ———————————
<?php//框架核心 视图类namespace core;use League\Plates\Engine;class View extends Engine{public $template;public function __construct($path){$this->template = parent::__construct($path);}}
UsersController.php
<?phpnamespace controllers;class UsersController{public $model;public $view;public function __construct($model,$view){$this->model = $model;$this->view = $view;}public function index(){$num = 10;$page = $_GET['p'] ?? 1;$offset = ($page - 1) * $num ;//用户信息总数据$orders = $this->model->select('order',['id','name','pro','price'],['LIMIT'=>[$offset,$num]]);//数据表总数据条数$count = $this->model->count('order');//获取总页数$pages = ceil($count/ $num );//将数据渲染到模板上(模板赋值同步完成)return $this->view->render('user/list',["pages"=>$pages,"orders"=>$orders,"page"=>$page]);}}
UsersModel.php
<?phpnamespace models;use core\Model;//用户自定义模型通常跟一张数据表对应class UsersModel extends Model{public function __construct(){parent::__construct();}}
Views>user>list.php，不含分页代码
分页代码查看：PHP原生态！控制+模型+列表渲染+算法分页
