How to get key of the item in laravel collection?
提问by zarcel
I pass a collection to the blade templating engine and in there I iterate over it. I want to display items position in the array. I thought of using items key, how do I extract it from the collections items?
我将一个集合传递给刀片模板引擎，然后在那里迭代它。我想显示数组中的项目位置。我想到了使用 items 键，如何从集合项中提取它？

No need to overcomplicate things.
没有必要把事情复杂化。
// in your controller
return view()->with('collection', $collection);
// in your view
@foreach($collection as $index => $item)
{{ $index }}
@endforeach
