Laravel Blade: Increment variable by 1 each time?

Question

Using Laravel blade template, is there a way to include a variable and increase each time in the foreach or what is better approach?

For example:

@foreach($categories as $category)   <li><a href="#tab_c1" role="tab" data-toggle="tab">{{$category->name}}</a></li> @endforeach 

In the foreach block, the value from #tab_c1 will need to be increase. eg: #tab_c1, #tab_c2, #tab_c3

Answer 1

Add iterator to @foreach:

@foreach($categories as $key => $category)   <li @if ($key === 0) class="active" @endif>     <a href="#tab_c{{$key+1}}" role="tab" data-toggle="tab">       {{$category->name}}     </a>   </li> @endforeach 

{{$key+1}} in my example because in PHP iterator starts at 0.
