PHP-dä OOP-de umumy metodlaryň miras alynyşy

Wiçe-klassy ene-klassyň ähli umumy metodlaryny miras alyp biler. Geliň mysal bilen göreli. Bizde aşakdaky metodlary bar klas bolsun:

php<?php
  class User {
    private $name;
    
    public function setName($name) {
      $this->name = $name;
    }
    public function getName() {
      return $this->name;
    }
  }
?>

Bu klasdan aşakdaky klas miras alsyn:

php<?php
  class Student extends User {
    
  }
?>

Geliň metodlaryň miras alyndygyny barlalyň. Täze student objektini döredeliň:

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

Ona miras alynan metoddan peýdalanyp, adyny belgileýäris:

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

Ona miras alynan metoddan peýdalanyp, adyny okalyň:

php<?php
  $name = $student->getName();
  echo $name;
?>
