How to get domain root url in Laravel 4?

UPDATE (2017-07-12)

A better solution is actually to use Request::getHost()

Previous answer:

I just checked and Request::root(); does return http://www.example.com in my case, no matter which route I’m on. You can then do the following to strip off the http:// part:

if (starts_with(Request::root(), 'http://'))
{
    $domain = substr (Request::root(), 7); // $domain is now 'www.example.com'
}

You may want to double check or post more code (routes.php, controller code, …) if the problem persists.

Another solution is to simply use $_SERVER['SERVER_NAME'].
