<?php
namespace App\Http\Middleware;
 
use Closure;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Config;
use Illuminate\Support\Facades\Session;
 
class Language
{
 /**
  * @param $request
  * @param Closure $next
  * @return mixed
  */
 public function handle($request, Closure $next)
 {
  if (Session::has('language') AND in_array(Session::get('language'), Config::get('app.locales'))) {
   App::setLocale(Session::get('language'));
  }
  else { // This is optional as Laravel will automatically set the fallback language if there is none specified
   App::setLocale(Config::get('app.locale'));
  }
  return $next($request);
 }
 
}
