Are you talking about the TLD changing or using a dot instead of a forward slash?

Using a dot instead of a slash.

So for example my url would look like this

www.mypage.com

but for the french it would look like this

www.mypage.fr

I made some changes to my code.

For my routes.php

Route::group(['suffix' => '{$tld}', 'before' => 'localization'], function() {
    Route::get('/', function() {
        return View::make('localization_test');
    });
});

For my filters.php

Route::filter('localization', function() {
	$tld = get_tld();
    App::setLocale($tld);
});

I also created a helpers.php

if ( ! function_exists('get_tld'))
{
    function get_tld()
    {
        $matches = array();
        preg_match('/laravel-local(.[a-zA-Z]+)/', Request::root(), $matches);
        $tld = $matches[1];

        return $tld;
    }
}

This picks up the .com, but when I try to change the .com into a .fr I get this error

Not Found

The requested URL /laravel-local.fr/public/ was not found on this server.

I'm sorry if this annoys anyone, but I'm a bit desperate at the moment. Can someone please help

Can someone please help

Have you got all the registered domains setup? A TLD means it is a different website.

At the moment I'm using my localhost. I've made it into a virtual host server

You can do it on your local as long as you set up all the entries in your hosts file. It will not fly on a server unless you register all those domains.
