What are the potential pitfalls of using session_register() for session management in PHP?

Using session_register() for session management in PHP is not recommended as it has been deprecated since PHP 5.3.0 and removed in PHP 5.4.0. This function is no longer supported due to security concerns and potential vulnerabilities in session management. It is advised to use the $_SESSION superglobal array for managing sessions in PHP. 

// Instead of using session_register(), use $_SESSION superglobal array
$_SESSION['username'] = 'JohnDoe';
$_SESSION['email'] = 'johndoe@example.com';
