PHP OOP-da Özgerişlidäki Metodyň Ady

Aýratynlyklaryň adlaryny özgerişlide saklamak ýaly, metodlaryň adlaryny hem saklap bolýar. Bir syna görüň. Bizde User klassy we onuň aýratynlyk getterleri bar bolsun:

<?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;
		}
	}
?>

Bu klassyň obýektini dörediň:

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

Özgerişlide metod ady saklanylyr diýeliň:

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

Indi özgerişlide saklanan ada eýe bolan metody çagyryň:

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

Aşakdaky klass berlen:

<?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;
		}
	}
?>

Bu massiw berlen:

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

Employee klassyndan bir obýekt dörediň we onuň aýratynlyklaryna massiw elementleri arkaly ýüz tutuň.
