Finding last vector item in foreach?

Finding last vector item in foreach?

I need to know what the last item in the vector is so that when the last one does not add a comma:

Example:

SEM SABER QUAL É O ULTIMO ITEM
1,2,3,4,5,

SABENDO QUAL É A ULTIMA VIRGULA
1,2,3,4,5

I make a foreach in the variable, and increment a comma to the text, however in the last one it will not be necessary to add the comma because it is to the last one. I'm using LARAVEL 5.4 along with blade for HTML manipulation.

Follow the code:

@foreach($cliente->compras as $compra)
    {{$compra->produto}},
@endforeach

The way it is above, it is putting the last comma, but it is normal taking into account that it is not doing any logic to leave it.

If the item is part of a collection use the last as follows:

<?php
    $last = $cliente->compras->last();
?>

@foreach($cliente->compras as $compra)
    {{$compra->produto}}
    @if ($last->produto != $compra->produto) {{','}} @endif
@endforeach
