How can variables be used as a workaround for creating instances of classes represented by constants in PHP?

In PHP, constants cannot be used as class names directly when creating instances of classes. However, variables can be used in place of constants to dynamically create instances of classes. By storing the class name in a variable and then using that variable to instantiate the class, we can achieve the desired behavior. 

<?php

// Define a constant representing the class name
define('CLASS_NAME', 'MyClass');

// Store the class name in a variable
$className = CLASS_NAME;

// Create an instance of the class using the variable
$instance = new $className();

// Now $instance is an instance of MyClass
