How can session_status() be utilized effectively in PHP to manage session control?

To effectively manage session control in PHP, session_status() can be used to check the current status of the session. This function returns an integer value representing the status of the session (PHP_SESSION_DISABLED, PHP_SESSION_NONE, PHP_SESSION_ACTIVE). By checking the session status before starting a session, you can prevent unnecessary session_start() calls and ensure proper session management.

if (session_status() == PHP_SESSION_NONE) {
    session_start();
}
