url facade in laravel 5 -

-

in l4 worked perfectly:

<a href="{{ url::to('autor/'.$o->surname)}}">{{$o->surname}}</a>

in l5 produces blank screen

and need resort this:

<a href="autor/{{ url::to($o->surname)}}">{{$o->surname}}</a>

how adjust syntax make work?

where docs me?

laravel 5 uses {{$var}} escape content , use {!!$var!!} echo unescaped strings
