Property Name from Function in OOP in PHP

The property name of an object can also be taken from a function. Let's see how it's done. Let's say we have the following class User:

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

Let's create an object of this class:

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

Suppose we have the following function:

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

Let's access the object's property, the name of which is returned by our function:

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

The following class is given:

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

The following functions are given:

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

Create an object of the Employee class, and then access its properties through the results of executing the functions.
