How to get the number of elements in a Bitrix section without subsections?

Question

PHP

Hello!
The standard template has this way of counting elements

$arItemFilter = CAllCorp::GetCurrentSectionElementFilter($arResult["VARIABLES"], $arParams);
$itemsCnt = CCache::CIblockElement_GetList(array("CACHE" => array("TAG" => CCache::GetIBlockCacheTag($arParams["IBLOCK_ID"]))), $arItemFilter, array());

But for unknown reasons, in some cases it returns 0, even if there are elements in the section.
Tell me how to return exactly the number of elements in the section, not taking into account the subsections. You can say the number of products that are displayed on the page, and if this page has subsections, then they and their content are not taken into account.

CIBlockSection::GetSectionElementsCount($SectionID);

returns the number of section items along with subsections
Thanks in advance.

Try something like this:

<?
  $arFilter = array('IBLOCK_ID' => 8, 'DEPTH_LEVEL'=>'1', 'SECTION_ID'=false);
  $res = CIBlockElement::GetList(false, $arFilter, array('IBLOCK_ID'));
  if ($el = $res->Fetch()){
    echo GetMessage("CT_CMM").$el['CNT'];
  }
?>
