Path methods helps easy access to application related paths easily from anywhere.

public_path()

This method returns the fully qualified public path of the application. which is the public directory.

$path = public_path();

    Urls

url()

The url function generates a fully qualified URL to the given path. if your site is hello.com

echo url('my/dashboard');

would return

if nothing is passed to the url method it would return an instance of Illuminate\Routing\UrlGenerator, and it could be used like this

would return current url

echo url()->current();

echo url()->full();

echo url()->previous();
