To keep your code DRY, and if your content comes from your model you should adopt a slightly different approach. Edit your model like so (tested in L5.8):
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;
class Comment extends Model
{
public function getShortDescriptionAttribute()
{
return Str::words($this->description, 10, '...');
}
}
?>
Then in your view :
{{ $comment->short_description }}
