Practical Application of Magic Methods in OOP in PHP

Задание 1

Let's say we have the following User class with getters and setters for properties:

php<?php
  class User
  {
    private $name;
    private $age;
    
    public function getName()
    {
      return $this->name;
    }
    
    public function setName($name)
    {
      if ($name != '') {
        $this->name = $name;
      }
    }
    
    public function getAge()
    {
      return $this->age;
    }
    
    public function setAge($age)
    {
      if ($age >= 0 and $age <= 70) { // check age
        $this->age = $age;
      }
    }
  }
?>

Rewrite the code of this class so that instead of getters and setters, the magic methods __get and __set are used.
