How do you access the loop index on a foreach loop outside the blade template?
By using the @foreach blade template I know that we can access the loop index with this $loop->index, but is there something similar outside the blade template that I can use to access the loop index? Like for example, I want to access the loop index on a model controller.

Uhm I mean how do I access the loop index inside the foreach? I have this code:
foreach($request->size as $size) {
$product->sizes()->attach($size, ['price' => $request->"loop index here"]);
}
I have a data from the request that has a name of price_0, price_1, price_2, So I want to access the loop index so I can get the value of each of them while looping the size.

Each row increases from 0
$item[0]->whatever
$item[1]->whatever
$item[2]->whatever
Etc
Something like that depending on if it's a complete array or an array of objects.

name your form elements differently and you don't have to mess about with this stuff
if your form items are named like size[] and price[] then your request receives two independent arrays
name them instead like items[]size and items[]price then you end up with a single array you can iterate over where each item has a size and a price attribute
a simple change in your form makes handling the data much easier

Oh thanks a lot, I would never have thought about it, I will try it out, not sure yet how it works.

I've tried what you've said I named them items[]size and items[]price. Sorry I'm quite confused so they're mixed into one array so, how do I access only the sizes or price?
