Is it possible to create session constants in PHP similar to the "final" modifier in Java?

In PHP, there is no direct equivalent to the "final" modifier in Java that can be used to create constants within a session. However, you can achieve a similar effect by using regular PHP constants and storing them in the session. By defining constants using the define() function and then storing them in the session, you can ensure that the values remain constant throughout the session.

<?php
// Define a constant
define('SESSION_CONSTANT', 'value');

// Start the session
session_start();

// Store the constant in the session
$_SESSION['session_constant'] = SESSION_CONSTANT;

// Access the constant from the session
echo $_SESSION['session_constant'];
?>
