localization issue

What about a basic if control ? I use it to check if language segment of my url is empty or not. I have changed my codes for you

PHP Code:

public function index(){

        $lang = $this->request->uri->getSegment(1);

        if($lang == 'en'){
            return redirect()->to(site_url('/en/offline'));
        } 


I tried checking the language with segment feature but you can check it via localization as well

PHP Code:

$locale = $this->request->getLocale();
if($locale == 'en'){
//goes here..
}
