        )

)

There is the last element of the array [Retail price],
I do foreach and the last element that "retail price" is not displayed, the penultimate one is displayed again.

debug($arResult["ITEMS"] );
foreach($arResult["ITEMS"] as $key=>$arItem) {
     debug($key);
     debug($arItem);
}

Output of the last iteration

That is, the key displays the correct one, but the element itself does not ...

Answer 1

Guys, I have not figured out the real reason.
But I fixed it simply:
foreach($arResult["ITEMS"] as $key=>$arItem)
was replaced with
foreach($arResult["ITEMS"] as $key=>$item)

Answer 2

So if I'm not mistaken it's not in the $arResult[items] subarray it's the last element of the $arResult array.
Although, according to your example, it should be ...
Sorry, I was mistaken)
