Blade Foreach: first/last item of the array
Blade templates are mostly for viewing data. But sometimes we do need to add some checks and IF-structures. One of the tricky examples – loop through @foreach but do some action only on first/last element of the array. Blade doesn’t have that functions in itself, so what do we do?
Update February 2018: In Laravel 5.3+ you can use $loop variable inside your blade loops. This variable holds useful information like current loop index and whether this is the first or last iteration through the loop.
This is how you check for the first item:
|
1 2 3 4 5 6 7 |
@foreach ($menu as $item) <div @if ($loop->first) class="hidden" @endif> <h2>{{ $item->title }}</h2> </div> @endforeach |
Similarly, we can check for the last item in the loop:
|
1 2 3 4 5 6 7 |
@foreach ($menu as $item) <div @if ($loop->last) class="no_margin" @endif> <h2>{{ $item->title }}</h2> </div> @endforeach |

Under the hood, Blade files are actually transformed into plain PHP. So the trick here is that we can use pretty much any core PHP function we want. And with arrays we have two useful functions to get the first and last element of the array:
- end($array) – advances array’s internal pointer to the last element, and returns its value.
- reset($array) – rewinds array’s internal pointer to the first element and returns the value of the first array element.
So how does it look in actual Blade example? Let’s say we want to hide every div element except for the first one:
|
1 2 3 4 5 6 7 |
@foreach ($menu as $item) <div @if ($item != reset($menu)) class="hidden" @endif> <h2>{{ $item->title }}</h2> </div> @endforeach |

Similar example – what if we want to add a CSS class to the last menu item?
|
1 2 3 4 5 6 7 |
@foreach ($menu as $item) <div @if ($item == end($menu)) class="no_margin" @endif> <h2>{{ $item->title }}</h2> </div> @endforeach |
That’s it. As you can see, Blade is not only a template engine, it has all power of core PHP structures and functions.
Nice! Just needed that today!
Not the best solution in my opinion. What if your array looks like this: [1, 1, 2, 2] then it will not work. My suggestion: use an index and test against that variable:
@foreach($array as $i => $item)
@if($i == 0) first item @endif
@if($i == count($array) – 1) last item @endif
@endforeach
Sweet idea! Though, I’m not sure that’s within the scope of how Blade was written to be honest.
What about this:
@if ( $resultado != $resultados->last() )
@endif
You could get the last item of a collection, be the native method last()
awesome lautaro thanks for it
That worked perfectly for me.
As for Laravel 5.3+, you can use the $loop variable
@foreach($array as $i => $item)
@if($loop->last) last item @endif
@endforeach
