Here is quick post, which can help you to get base url or home page url of your laravel application. I think many times we need to get site URL for something share or link, so you can get that using url helper and URL facade. Both way are same you can use that anywhere i mean in controller or view. so let's see.
<pre class="prettyprint lang-php">
$url = URL::to("/");
$url2 = url('/');
