PHP da OOP da Meros Olishda Privat Xususiyatlar

Privat xususiyatlar meros olinmaydi. Ammo voris ular bilan ota-onaning ommaviy usullari orqali manipulyatsiya qilishi mumkin. Keling, amalda ko'rib chiqaylik. Aytaylik, bizda quyidagi ota-ona sinfi mavjud privat xususiyat va uning getter va setter bilan:

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

Aytaylik, ota-onadan quyidagi voris meros qoladi:

<?php
	class Student extends User {
		
	}
?>

Keling, vorisning ob'ektini yaratamiz:

<?php
	$student = new Student;
?>

Keling, uning privat xususiyatini yozish uchun ota-onaning usulidan foydalanamiz:

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

Keling, uning privat xususiyatini o'qish uchun ota-onaning usulidan foydalanamiz:

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

Quyidagi ota-ona sinfi berilgan:

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

Employee sinfini yarating, bu ota-onadan meros oladi.

Employee sinfining ob'ektini yarating va meros qilib olingan setter va getter larni chaqiring.

Employee sinfida quyidagi usulni bajaring:

<?php
	public function getFull() {
		return $this->name . ' ' . $this->surn;
	}
?>

Usul kodining xatolikka olib kelishiga ishonch hosil qiling.
