What are the benefits of using $_SESSION['variable'] over session_register() for managing session data in PHP?

Using $_SESSION['variable'] is preferred over session_register() for managing session data in PHP because session_register() is deprecated as of PHP 5.3.0 and removed in PHP 5.4.0. Additionally, using $_SESSION['variable'] is more secure and follows the current best practices for managing session data in PHP.

<?php
// Start the session
session_start();

// Setting a session variable
$_SESSION['variable'] = 'value';

// Accessing the session variable
echo $_SESSION['variable'];
?>
