Multilingual URLs in Laravel 4

 * Multilingual URLs in Laravel 4

//config/app.php

return array(
    ...
    'languages' => array('en', 'gr'),
    ...
);

// filters.php

App::before(function($request)
{
    $uri = $request->server->get('REQUEST_URI');
    foreach(Config::get('app.languages') as $language){
        if(preg_match('/^\/'.$language.'(\/|\z|\?.*|#(.*))/', $uri)){
            Config::set('app.locale', $language);
            $newUri = '/'.substr($uri, 3);
            $request->server->set('REQUEST_URI', $newUri);
        }
    }
});

Maybe App::before can be replaced by this code

App::before(function($request)
{
    // default browser language
    $language = substr($request->server->get('HTTP_ACCEPT_LANGUAGE'), 0, 2);

    // language set from route
    if (null !== $request->segment(1)) {
        $routeLanguage = $request->segment(1);
        if (in_array($routeLanguage, Config::get('app.languages'))) {
            $language = $routeLanguage;
        }
    }
    // set the language
    Config::set('app.locale', $language);
    App::setLocale($language);
});

In my case, I wanted to keep the language in URL.
