What is the significance of using $_SESSION instead of session_register in PHP?

Using $_SESSION instead of session_register in PHP is significant because session_register is deprecated as of PHP 5.3.0 and removed in PHP 5.4.0. Therefore, it is recommended to use $_SESSION to register variables in the session. This ensures compatibility with newer versions of PHP and follows best practices for session handling in PHP. 

// Using $_SESSION to register variables in the session
session_start();

$_SESSION['username'] = 'JohnDoe';
$_SESSION['email'] = 'johndoe@example.com';
