PHP OOP-da nesil klasslaryň metodlary

Nesil klassy öz metodlaryna eýe bolup biler. Mysal üçin, talypymyza okuw ýyly üçin getter we setter goşalyň:

php<?php
  class Student extends User {
    private $year;
    
    public function setYear($year) {
      $this->year = $year;
    }
    public function getYear() {
      return $this->year;
    }
  }
?>

Nesil klassda onuň şahsy metodlary hem, miras alnan metodlar hem elýeterli bolar. Geliň barlap göreli. Klassyň obýektini döredeliň:

php<?php
  $student = new Student;
?>

Ona miras alnan metod arkaly adyny, ýöne öz metodymyz arkaly okuw ýylyny belgileýeliň:

php<?php
  $student->setName('john');
  $student->setYear(1);
?>

Onuň adyny we okuw ýylyny okalyň:

php<?php
  $name = $student->getName();
  $year = $student->getYear();
  
  echo $name . ' ' . $year;
?>
