debugging of data read with phpQuery

Hello,
Can you advice some tools(php7/laravel5) for debugging/review of data read with phpQuery?
I mean when I need to get data-attribute of H2 tag I write:

1. $pq = pq($nextContainerDivItem);
2. $nextTitle= $pq->find('h2.s-access-title');
3. echo '<pre>$nextTitle::</pre>';
4. dump($nextTitle);
5. $next_title= !empty($nextTitle->attr('data-attribute') ) ? $nextTitle->attr('data-attribute') : '';

I googled the right decision and now in $next_title valid value, but debugging the output

is not really usefull, as I could not review the value in dumping: I suppose to find it in path elements->attributes,
but as you see at printscreen.

If there is better of dumping ? If possible with options to show some nodes. Say not empty or specifile in path, as if ["elements->attributes"]
specified show it opened.

Also when I write wrong path/class I have some output like in printscreen above.
I would like in some way to show if the node was found or not?
If there is way to make it?
Which debugging tools do you use with phpQuery requests ?

Thanks!
