What are the potential security risks associated with using the session_register function in PHP?

Using the session_register function in PHP can potentially lead to security risks such as register_globals being enabled, which can allow for variable injection attacks. It is recommended to avoid using session_register and instead use the $_SESSION superglobal array to store session variables securely. 

// Avoid using session_register
session_register('variable_name');

// Use $_SESSION superglobal array instead
$_SESSION['variable_name'] = $value;
