Using the $loop variable in foreach loops in Laravel Blade

Laravel provides simple blade template which provides many directive to use direct in html code. With blade engine you can write core PHP code with @php directive. In Blade, you can also use loop directive like @for, @foreach, @forelse and @while instead of loop condition. While looping, you may use $loop variable for valuable information.

In this article, we will show $loop variable and its properties to get many useful information.

If you want to check whether it is first or last iteration of the loop, then you may use this.

@php
$numbers = [3, 2, 8, 12, 2, 6];
@endphp

@foreach ($numbers as $number)
    @if ($loop->first)
        {{ $number }} {{-- 3 --}}
    @endif

    @if ($loop->last)
        {{ $number }} {{-- 6 --}}
    @endif
@endforeach

You may get the index of the loop, which starts from 0.

@php
$numbers = [3, 2, 8, 12, 2, 6];
@endphp

@foreach ($numbers as $number)
    @if ($loop->index == 2)
        {{ $number }} {{-- 8 --}}
    @endif
@endforeach

or the iteration of the loop, which starts from 1.

@php
$numbers = [3, 2, 8, 12, 2, 6];
@endphp

@foreach ($numbers as $number)
    @if ($loop->iteration == 3)
        {{ $number }} {{-- 8 --}}
    @endif
@endforeach

If you want to get remaining iterations of the loop, you may use.

@php
$numbers = [3, 2, 8, 12, 2, 6];
@endphp

@foreach ($numbers as $number)
    @if ($loop->iteration == 1)
        {{ $loop->remaining }} {{-- 5 --}}
    @endif
@endforeach

You may use count property to get total number of items in the array.

@php
$numbers = [3];
@endphp

@foreach ($numbers as $number)
    {{ $loop->count }}
@endforeach

Same way you may find whether the current iteration is even or odd.

@php
$numbers = [3, 2, 8, 12, 2, 6];
@endphp

@foreach ($numbers as $number)
    @if ($loop->even)
        {{ $number }}
    @endif
@endforeach

If you are iterating loop within loop, you may get the depth of the loop.

@foreach ($users as $user)
    @foreach ($user['articles'] as $article)
        {{ $loop->depth }}
    @endforeach
@endforeach

While looping internal loop, you may get parent loop details with parent property.

@foreach ($users as $user)
    @foreach ($user['articles'] as $article)
        {{ $loop->parent->iteration }}
    @endforeach
@endforeach

I hope it will help you.
