Thanks, but it won't work in my case.

    foreach(range(1, 100) as $key => $value)
    {
        if(!($key % 3))
        {
           <div class="row">
             <div class="col-md-4">
                 // laravel data goes here
             </div>
           </div>
        }
    }

So as you can see it will just print every col-md-4 in a new row, that's not what i needed. I need:

<div class="row">
<div class="col-md-4"></div>
<div class="col-md-4"></div>
<div class="col-md-4"></div>
</div>

Thanks again, but it won't work as i said above:

   foreach(range(1, 12) as $key => $value)
    {

        if(!($key % 3))
        {
			echo "<div class='row'></div>";
        }
		
		echo '<div class="col-md-4">Laravel</div>';

    }

it will output:

<div class='row'></div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>

<div class='row'></div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>

<div class='row'></div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>

<div class='row'></div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>

I need to wrap col-md-4's in to a row class. In your construction that won't happen.

Output of your code would be:

<div class='row'>
<div class="col-md-4">Laravel</div>
</div>

<div class='row'>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
</div>

<div class='row'>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
</div>

<div class='row'>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
</div>

<div class='row'>
<div class="col-md-4">Laravel</div>
<div class="col-md-4">Laravel</div>
</div>

How to deal with the first row with single col-md? And it should output 4 rows instead of 5. Thanks for your help.

Ended up with such construction:

		<div class="row">
		@foreach(range(1, 12) as $key => $value)
		
		@if(!($key % 3) and $key > 0)
		</div>
		<div class="row">
		@endif

		@foreach($category->articles()->orderBy('created_at', 'DESC')->paginate(12) as $article)
		<div class="col-md-4">
			<div class="video">
				<a href="/article/{{ $article->slug }}"><img class="img-responsive" src="/imagecache/mainart/{{ $article->image }}" /></a>
				<p>{{ strip_tags(str_limit($article->body, $limit = 90, $end = '...')) }}</p>
			</div><!--video-->
		</div><!--/col-md-4-->
		@endforeach

		@endforeach
		</div>

but it outputs 4 rows and 12 col-md's in each row (it shoud be 3 col-md's in a single row, not 12)
