Question

1C-Bitrix

There is a catalog.section.list, the template is formed as follows:

<?
    $rs = new CDBResult;
    $rs->InitFromArray($arResult['SECTIONS']);
    $rs->NavStart(10);
    if($rs->IsNavPrint())
    {
        while ($arSection = $rs->Fetch()):
            $db_list = CIBlockSection::GetList(Array($by=>$order),
                $arFilter = Array("IBLOCK_ID"=>$arSection["IBLOCK_ID"], "ID"=>$arSection["ID"]), true, $arSelect=Array());
            while($ar_result = $db_list->GetNext()){
                $sectCountry = $ar_result['UF_STRANA'];
            }
            ?>
        <?     $file = CFile::GetPath($arSection["UF_ICO_TV"]);
            ?>
            <div class="tests__item tests-item">
                <a href="<?=$arSection["SECTION_PAGE_URL"]; ?>">
                    <div class="tests-item__image">
                        <img src="<?=$arSection['PICTURE']['SRC']?>" alt="">
                    </div>
                </a>
            </div>

How to sort by the creation date of the first level section (the newer the section, the higher it is)
The array with sections is in $arResult['SECTIONS']
There is an option to sort the array manually before the loop, but are there regular sorting functions?

Answer 1

In your case, only do the sorting yourself, it will not be regular
