Is it necessary to use session_regenerate_id() on every page request in a protected area in PHP?

It is not necessary to use session_regenerate_id() on every page request in a protected area in PHP. However, it is recommended to use it periodically to enhance security by preventing session fixation attacks. It can be used after a successful login or when sensitive information is accessed. 

// Start the session
session_start();

// Check if the session needs to be regenerated
if (isset($_SESSION['regenerate']) && $_SESSION['regenerate'] == true) {
    session_regenerate_id();
    $_SESSION['regenerate'] = false;
}

// Other protected area code here
