PHP da OOP da Funksiya Orqali Xususiyat Nomiga Murojaat

Obyekt xususiyatining nomini ham funksiyadan olish mumkin. Buni qanday amalga oshirishni ko'rib chiqaylik. Quyidagi User klassimiz bor deb faraz qilaylik:

<?php
	class User
	{
		public $name;
		public $surn;
		
		public function __construct($name, $surn)
		{
			$this->name = $name;
			$this->surn = $surn;
		}
	}
?>

Ushbu klassning obyektini yaratamiz:

<?php
	$user = new User('john', 'smit');
?>

Quyidagi funksiyamiz bor deb faraz qilaylik:

<?php
	function getProp()
	{
		return 'name';
	}
?>

Keling, obyekt xususiyatiga murojaat qilaylik, uning nomi bizning funksiyamiz tomonidan qaytariladi:

<?php
	echo $user->{getProp()}; // 'john' ni chiqaradi
?>

Quyidagi klass berilgan:

<?php
	class Employee
	{
		public $name;
		public $salary;
		public $position;
		
		public function __construct($name, $salary, $position)
		{
			$this->name = $name;
			$this->salary = $salary;
			$this->position = $position;
		}
	}
?>

Quyidagi funksiyalar berilgan:

<?php
	function getProp1()
	{
		return 'name';
	}
	function getProp2()
	{
		return 'salary';
	}
?>

Employee klassining obyektini yarating, keyin uning xususiyatlariga funksiyalarni bajarish natijalari orqali murojaat qiling.
