Create PHP Object from JSON Content

Consider that you have example.json with the following content:

{
  "firstName": "Temuri",
  "lastName": "Takalandze",
  "active": true,
  "position": {
    "title": "Developer",
    "department": {
      "title": "IT"
    }
  }
}

Department.php

<?phpclass Department
{
    /**
     * @var string
     */
    private $title;…
