1C-Bitrix

My page receives $_REQUEST['CODE'] of a section, how can I get the section ID knowing its character code ?
Tried like this

$rsSections = CIBlockSection::GetList(array(),array('IBLOCK_ID' => 25, '=CODE' => $_REQUEST['CODE']),false,array("IBLOCK_SECTION_ID "));
  if ($arSection = $rsSections->Fetch())
  {
    echo 'ID секции: '.$arSection['IBLOCK_SECTION_ID'];
  }

does not display

Answer 1

Add an ID to the selection, array("IBLOCK_SECTION_ID", "ID")
