What are the drawbacks of using the session_register function in PHP for form data?

Using the session_register function in PHP for form data is not recommended as it is deprecated and considered insecure. It can potentially expose sensitive information to security risks such as session hijacking. Instead, it is recommended to use the $_SESSION superglobal to store form data securely. 

<?php
session_start();

// Store form data in $_SESSION superglobal
$_SESSION['username'] = $_POST['username'];
$_SESSION['email'] = $_POST['email'];
// Additional form data can be stored in a similar manner

// Redirect to another page after storing form data
header("Location: another_page.php");
exit;
?>
