What or how to replace the constructor?

Question

PHP

There is a base controller class in the constructor of which the user's authorization is checked. There was a problem when creating child classes: If I create a new constructor in child classes, it overrides the base class constructor.
Why am I trying to use a constructor in child classes? - One example is the creation of a specific page model object.
Is it possible to somehow replace the constructor? Or maybe there is some other way?

Answer 1

class A {
  public $firstname;

  public function __construct($firstname) {
    $this->firstname = $firstname;
  }
}

class B extends  A {

  public $lastname;

  public function __construct($firstname,$lastname) {
    parent::__construct($firstname);
    $this->lastname= $lastname;
  }
}

$class = new B('Vasya','Pupkin');

echo $class->firstname , $class->lastname;
