正确使用Laravel来自非MVC PHP

Question

I am making an app and I am getting Laravel to do what I want but I think I am using it in the worst possible way.

I am doing things like this in views

<?php $array = explode(",", $comment->fields); ?>
@foreach ($array as $x)
<span class="post-tag">
{{ $x }}</span>
@endforeach

Should I do this in the controller? Or the Model? and how?
