PHP da OOP da Assotsiativ Massiv Elementidan Xususiyat Nomi

Keling, endi obyekt xususiyatiga assotsiativ massiv elementidan olingan nom bilan qanday murojaat qilishni ko'ramiz. Faraz qilaylik, bizda quyidagi User klassi mavjud:

<?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');
?>

Faraz qilaylik, xususiyatlar massivi berilgan:

<?php
	$props = ['prop1' => 'name', 'prop2' => 'surn'];
?>

Obyekt xususiyatiga murojaat qilamiz, uning nomi bizning massivimizning elementida saqlanadi:

<?php
	echo $user->{$props['prop1']}; // '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;
		}
	}
?>

Massiv berilgan:

<?php
	$arr = [
		'prop1' => 'name',
		'prop2' => 'salary', 
		'prop3' => 'position'
	];
?>

Employee klassining obyektini yarating, so'ngra uning xususiyatlariga massiv elementlari orqali murojaat qiling.
