How to get only 10 elements from an infoblock?

Question

1C-Bitrix

As I understand it logically, if you set the number of elements to be displayed in the 4th parameter, then this should work, but it would work for a site that has pagination. And I have a task to make it so that only 10 elements would be returned to me specifically for the GetList request.
Here is a code example of how I do it:

$arOrder = [
                        'ID' => 'asc'
                    ];
                    $arFilter = [
                        'SECTION_ID'  => $SECTION_ID,
                        'ACTIVE'      => 'Y',
                        '>ID'         => $IdElement
                    ];
                    return CIBlockElement::GetList($arOrder, $arFilter, false, Array("nTopCount"=>10), ['ID', 'NAME', 'IBLOCK_SECTION_ID']);

This is the code inside the function, all variables for filtering are passed to it.
I also tried nPageSize, it doesn't work

Answer 1

I didn’t figure out how to do this specifically, so I sorted by ID => desc and then generated the array element I needed from the data that I received, inserted it at the beginning of the final array and at the output I received an array in the order I needed and with the ones I needed elements

Answer 2

$result = CIBlockElement::GetList(array('ID' => 'DESC'), array(), false, array('nTopCount' => 10), array('ID'));
while($item = $result->fetch()){
  $items[] = $item['ID'];
}
echo '<pre>' . print_r($items, true) . '</pre>';

everything is ok, it displays ten elements with the highest id
try to insert it (without your filters) - if everything is ok, then check your filters
