In what ways does the lack of a RestoreSettings() function limit the functionality and usability of the settings class?

The lack of a RestoreSettings() function limits the functionality and usability of the settings class by not providing a way to revert settings back to their original state. This can be problematic if a user wants to undo changes or if there is an error in setting new values. To solve this issue, we can implement a RestoreSettings() function that stores the original settings and allows them to be restored when needed. 

class Settings {
    private $originalSettings;
    private $currentSettings;

    public function __construct($settings) {
        $this->originalSettings = $settings;
        $this->currentSettings = $settings;
    }

    public function updateSetting($key, $value) {
        $this->currentSettings[$key] = $value;
    }

    public function restoreSettings() {
        $this->currentSettings = $this->originalSettings;
    }
}
