Laravel: Get base url

You can use the URL facade which lets you do calls to the URL generator

So you can do:

URL::to('/');

You can also use the application container:

$app->make('url')->to('/');
$app['url']->to('/');
App::make('url')->to('/');

Or inject the UrlGenerator:

<?php
namespace Vendor\Your\Class\Namespace;

use Illuminate\Routing\UrlGenerator;

class Classname
{
    protected $url;

    public function __construct(UrlGenerator $url)
    {
        $this->url = $url;
    }

    public function methodName()
    {
        $this->url->to('/');
    }
}

Laravel < 5.2

echo url();

Laravel >= 5.2

echo url('/');
