What are the potential issues with using session_register() in PHP and what are the recommended alternatives?

Using session_register() in PHP is deprecated as of PHP 5.3.0 and removed in PHP 5.4.0. This function is no longer recommended due to security concerns and potential vulnerabilities. It is recommended to use the $_SESSION superglobal array directly to set and retrieve session variables. 

// Instead of using session_register(), directly set session variables using $_SESSION
$_SESSION['variable_name'] = $value;
