In Laravel 5.x we have lang class which will help us to retrieving string in different languages that will help us to easily support multiple languages.

The folder structure for /resources/lang files are

/resources
    /lang
        /en
            messages.php
       /es
           messages.php

Example:

Language files always give an array of keyed strings.

<?php
return array(
    'welcome' => 'Welcome to our application'
);

Note: we can also change our default language by changing in the app/config/app.php configuration file.

App::setLocale('es');

Configuring The Locale

All the configuration of locale is stored in the config/app.php.We can also change the active language at runtime using the setLocale method on the App facade:

Example:

Route::get('welcome/{locale}', function ($locale) {
    App::setLocale($locale);

    //
});

By this way we can make our site multilingual.
