CODE EXAMPLE FOR PHP

laravel $loop->iteration

@foreach($listdata as $data)
	// normal iteration
		{{ $data->iteration() }}

	// if you using "paginate()" in your query, better use this iteration per-page below:
		// for example:
			// page 1 iteration = 1,2,3,4,5 ascending, 5,4,3,2,1 descending
			// and page 2 iteration will be = 6,7,8,9,10 ascending, 10,9,8,7,6 descending

        // iteration ascending (1,2,3,...)
            {{ $data->firstItem() + $loop->index }}

        // iteration descending (...,3,2,1)
            {{ ($data->total()-$loop->index) - (($data->currentpage()-1) * $data->perpage()) }}
@endforeach
