Property Setters in OOP in PHP

For writing private properties, they also create methods called setters. Their names usually start with the word set. Let's create setters for the properties:

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;
    }
  }
?>

Let's test the work of getters and setters. Let's create an object of our class:

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

Using setters, set the property values:

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

Using getters, output the property values:

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