php - Laravel 8 display 4th, 5th and 6th elements of a collection

Solution:

If you're in a blade, using bootstraps containers, rows and cards:

<div class="container">
@foreach($players as $player)    
    @if($loop->first)
    <div class="row"> //first iteration, start a row
    @endif
    //each element is a cart
    <div class="card">
        <div class="card-header">
            
        </div>
        <div class="card-body" style="padding: 3px">
        </div>
    </div> 
    @if(($loop->iteration % 3 == 1)&&(!$loop->last))
    //every 3rd iteration, and not the last, end the current row and start a new one
    </div>
    <div class="row">
    @endif
    @if($loop->last)
    </div>//if it's the last iteration, end the row
    @endif
@endforeach
</div>

This is just basic array looping, don't have to get complicated or fancy. More on the Laravel $loop variable here:

Solution:

I don't get well your use case, but you could use the method of the Collection class:

$players = Player::where('...')->get();

$chunks = $players->chunk(3);

foreach($chunks as $chunk) {
    foreach($chunk as $player) {
        // ...
    }
}

@foreach ($players->chunk(3) as $chunk)
    <div class="row">
        @foreach ($chunk as $player)
            <div class="col-xs-4">{{ $player->name }}</div>
        @endforeach
    </div>
@endforeach
