Laravel uses a clean file-based system where each language has its own folder. These folders store translation strings that can be reused across views, controllers, and APIs.
This approach keeps your code organized and your translations easy to manage.
Supported Languages in This Setup
This implementation includes:
- English (en) – Default language
- Bangla (bn) – For Bengali users
- Arabic (ar) – With RTL support
- French (fr) – For European and global users
Each language has its own translation file, ensuring clarity and scalability.
Create Language Directories

resources/lang/en/messages.php
<?php
return [
'welcome' => 'Welcome',
'login' => 'Login',
'logout' => 'Logout',
'dashboard' => 'Dashboard',
];
resources/lang/bn/messages.php
<?php
return [
'welcome' => 'স্বাগতম',
'login' => 'লগইন',
'logout' => 'লগআউট',
'dashboard' => 'ড্যাশবোর্ড',

<?php
return [
'welcome' => 'مرحباً',
'login' => 'تسجيل الدخول',
'logout' => 'تسجيل الخروج',
'dashboard' => 'لوحة التحكم',

resources/lang/fr/messages.php
<?php
return [
'welcome' => 'Bienvenue',

'logout' => 'Déconnexion',
'dashboard' => 'Tableau de bord',

config/app.php
'locale' => 'en', 'fallback_locale' => 'en',
routes/web.php
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Session;
Route::get('lang/{locale}', function ($locale) {
if (! in_array($locale, ['en', 'bn', 'ar', 'fr'])) {
abort(400);
}
Session::put('locale', $locale);
App::setLocale($locale);
return redirect()->back();
});
app/Http/Middleware/SetLocale.php
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\App;
use Illuminate\Support\Facades\Session;
class SetLocale
{
public function handle($request, Closure $next)
{
if (Session::has('locale')) {
App::setLocale(Session::get('locale'));
}
return $next($request);
}
}
app/Http/Kernel.php
protected $middlewareGroups = [

\App\Http\Middleware\SetLocale::class,

];
Use Translation in Blade
<h1>{{ __('messages.welcome') }}</h1>
<a href="#">{{ __('messages.login') }}</a>
Language Switcher (Blade UI)
<ul>
<li><a href="{{ url('lang/en') }}">English</a></li>
<li><a href="{{ url('lang/bn') }}">বাংলা</a></li>
<li><a href="{{ url('lang/ar') }}">العربية</a></li>
<li><a href="{{ url('lang/fr') }}">Français</a></li>
</ul>
Blade Layout Example
<html lang="{{ app()->getLocale() }}"
dir="{{ app()->getLocale() == 'ar' ? 'rtl' : 'ltr' }}">
Use Localization in Controller
return response()->json([
'message' => __('messages.welcome')
]);
