Practice Working with Models in MVC in PHP

Suppose you have a table named page in your database with some records. Let's create a model Page with two methods. The first method will retrieve one record by its id, and the second method will retrieve an array of records from a range of id:

/project/models/Page.php<?php
  namespace Project\Models;
  use \Core\Model;
  
  class Page extends Model
  {
    public function getById($id)
    {
      return $this->findOne("SELECT * FROM page WHERE id=$id");
    }
    
    public function getByRange($from, $to)
    {
      return $this->findMany("SELECT * FROM page WHERE id>=$from AND id<=$to");
    }
  }
?>

Now let's work with our model in the controller:

project/controllers/PageController.php<?php
  namespace Project\Controllers;
  use \Core\Controller;
  use \Project\Models\Page; // connect our model
  
  class PageController extends Controller
  {
    public function test() {
      $page = new Page; // create model object
    
      $data = $page->getById(3); // get record with id=3
      var_dump($data);
      
      $data = $page->getById(5); // get record with id=5
      var_dump($data);
      
      $data = $page->getByRange(2, 5); // records with id from 2 to 5
      var_dump($data);
    }
  }
?>
