Laravel 5 php DOMdocument

Ive been trying to find a way to use php DOMdocument in laravel 5.1 but I fail every time. I think I don't get how it works.

I need to get title and/or video ID from youtube page, or any other page.

Ive tried to include this simplehtmldom

and other things. But I always get server 500 error and don't know why.

Currently I have

$dom = new \DOMDocument();
$dom->loadHTML('https://www.youtube.com/watch?v=QQ7XJG0Z2ho');
$a = $dom->getElementsByTagName('title');

And on my view I just do

@if(isset($a))
    {{var_dump($a)}}
@endif

It returns

object(DOMNodeList)#171 (1) { ["length"]=> int(0) }

But this is not the title. Don't even know what this means. Can anyone tell what I'm doing wrong of maybe there is better way to do it?
