How to detect language preference in Laravel 5

Question

I want to detect my client language by getting the browser recommended language.

For Example, if you open the browser in Japan it will give me country code or countr

Answer 1

I just made a Middleware for this, it may be useful.

First you set $availableLangs the array of the available languages in your app, you may use config\app.php instead of initializing the array in the middleware as I did.

If the first language is available in the request language data, it sets the locale, if not, it will search the next one, and so on.

class GetRequestLanguage
{

    public function handle($request, Closure $next)
    {
        if (Session::has('locale')) {
            App::setLocale(Session::get('locale'));
        } else {
            $availableLangs = ['pt', 'en'];
            $userLangs = preg_split('/,|;/', $request->server('HTTP_ACCEPT_LANGUAGE'));

            foreach ($availableLangs as $lang) {
                if(in_array($lang, $userLangs)) {
                    App::setLocale($lang);
                    Session::push('locale', $lang);
                    break;
                }
            }
        }

        return $next($request);
    }
}
