Viseitaji za Sifa katika OOP kwa PHP

Kwa ajili ya kuandika sifa za kibinafsi pia hufanyika njia, ambazo huitwa viseitaji. Majina yao kwa kawaida huanza na neno set. Hebu tutengeneze viseitaji za sifa:

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

Hebu tuangalie utendakazi wa vivutaji na viseitaji. Tuunde kitu cha darasa letu:

php<?php
  $user = new User();
?>

Kwa kutumia viseitaji tuweke thamani za sifa:

php<?php
  $user->setName('john');
  $user->setSurn('smit');
?>

Kwa kutumia vivutaji tuandike thamani za sifa:

php<?php
  echo $user->getName();
  echo $user->getSurn();
?>
