Method Name from Variable in OOP in PHP

Similarly to storing property names in variables, you can also store method names. Let's look at an example. Suppose we have the following class User with property getters:

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

Let's create an object of this class:

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

Suppose a variable stores the method name:

<?php
	$method = 'getName';
?>

Let's call the method with the name from the variable:

<?php
	echo $user->$method(); // outputs 'john'
?>

Given the following class:

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

Given an array:

<?php
	$methods = [
		'method1' => 'getName',
		'method2' => 'getSalary',
		'method3' => 'getPosition',
	];
?>

Create an object of the Employee class, and then access its properties through the array elements.
