how to url in laravel code example

Example 1: previous url laravel

1. The cleanest way seems to be using the url() helper:
	{{ url()->previous() }}

2. URL::previous() works for me in my Laravel 5.1 project. Here is Laravel 5.1 
  doc for previous() method, which is accessible through URL Facade.

3. You can still try alternatives, in your views you can do:

	{{ redirect()->getUrlGenerator()->previous() }}
						OR
	{{ redirect()->back()->getTargetUrl() }}

Example 2: laravel use url

use Illuminate\Support\Facades\URL;

echo URL::current();
