Let’s get started.

Laravel Methods for Language Translation

In Laravel, there are following ways to do language translation:

• Lang::get()
• __()
• trans()

To understand about these i.e How to use?

Let’s do a laravel setup with language keys.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Settings Up Language Files

Here, we will assume two languages: French (fr) and English (en).

You need to create language keys into language respective files inside lang folder.

To create lang folder, open project terminal and run this command.

php artisan lang:publish

It will create lang folder into your application root. Next, we need to add language files into it.

Create Language Files

Create two folders say fr and en inside lang folder.

Next, create language keys file with name messages.php inside these folders.

Folders and file be like,

• /lang/fr/messages.php

• /lang/en/messages.php

French (fr) Language keys Settings,

<?php

return [
    "welcome" => "Bienvenue sur le tuteur Web en ligne",
    "introduction" => "L'équipe du tuteur Web en ligne vous aidera avec l'installation, la passerelle de paiement, les talons, les notifications push, les notifications jQuery, la requête AJAX, Livewire, les méthodes d'authentification et d'autres sujets."
];

    "introduction" => "The Online Web Tutor Team will assist you with Installation, Payment Gateway, Stubs, Push Notifications, jQuery Notifications, AJAX Request, Livewire, Authentication Methods, and other topics."
];

Setup Translation Controller

Open project terminal and run this command,

php artisan make:controller TranslationController

It will create a TranslationController.php file inside /app/Http/Controllers folder.

Open file and write this code into it,

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class TranslationController extends Controller
{
    public function translation()
    {
        //
    }
}

Next, you will see how to use language translation in this controller.

Laravel Language Translation Methods

You can use Laravel facade and helpers for language translation.

Method #1: Using Lang Facade

Import Lang facade,

use Illuminate\Support\Facades\Lang;

Call language key using get() method,

$message = Lang::get('messages.welcome',[],'fr'); // French language

$message = Lang::get('messages.welcome',[],'en'); // French language

Here, calling welcome key from language files.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Lang;

class TranslationController extends Controller
{
    public function translation()
    {
        $message1 = Lang::get('messages.welcome',[],'fr');
      
        $message2 = Lang::get('messages.welcome',[],'en');
     
        echo $message1;
      
        echo "<br/><br/>";
      
        echo $message2;
    }
}

Now, you need to setup a basic route to call this translation() method.

use App\Http\Controllers\TranslationController;

Route::get("/lang", [TranslationController::class, "translation"]);

Output,

{
    public function translation()
    {
        $message1 = __('messages.welcome',[],'fr');
      
        $message2 = __('messages.welcome',[],'en');
     
        echo $message1;
      
        echo "<br/><br/>";
      
        echo $message2;
    }
}

Here, you will see the use of laravel trans() helper function.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class TranslationController extends Controller
{
    public function translation()
    {
        $message1 = trans('messages.welcome',[],'fr');
      
        $message2 = trans('messages.welcome',[],'en');
     
        echo $message1;
      
        echo "<br/><br/>";
      
        echo $message2;
    }
}
