How can session management best practices be implemented in PHP to avoid errors like session_is_registered()?

The issue with using session_is_registered() in PHP is that it has been deprecated since PHP 5.3.0 and removed in PHP 5.4.0. To avoid errors related to this function, it is recommended to use isset() to check if a session variable is set instead. 

// Check if a session variable is set using isset()
if(isset($_SESSION['variable_name'])) {
    // Variable is set, do something
} else {
    // Variable is not set
}
