Receiving data from the infoblock section by section with caching, for example, for a landing page

Quite often I am asked to make a fairly voluminous page with content located in the infoblock. Where sections are sections of the page, and section items are section list items or settings. Here is the code that I use for most of these cases

  if (CModule :: IncludeModule ("iblock")) {
    $ cntIBLOCK_List = 50;

    $ cache = new CPHPCache ();
    $ cache_time = 3600 * 12 * 7; // cache for a week
    $ cache_id = 'preferences'. $ cntIBLOCK_List;
    $ cache_path = 'preferences';
    if ($ cache_time> 0 && $ cache-> InitCache ($ cache_time, $ cache_id, $ cache_path))
    {
        $ res = $ cache-> GetVars ();
        if (is_array ($ res ["preferences"]) && (count ($ res ["preferences"])> 0)) {
            $ preferences = $ res ["preferences"];
        }
        $ preferences ['CACHE'] = 'true';

    }
    if (! is_array ($ preferences))
    {
        $ preferences ['CACHE'] = 'false';

        $ arFilter = Array ('IBLOCK_TYPE' => 'content', 'IBLOCK_ID' => $ cntIBLOCK_List, 'GLOBAL_ACTIVE' => 'Y');
        $ arSelect = array ("ID", "IBLOCK_ID", "NAME", "CODE", "UF_ *");

        $ rsCityList = CIBlockSection :: GetList (Array (), $ arFilter, true, $ arSelect);

        while ($ item = $ rsCityList-> GetNext ()) {

            $ preferences [$ item ['ID']] = $ item;

            $ arSort = array ('SORT' => 'ASC', 'ID' => 'DESC');
            $ arFilter = array ('ACTIVE' => 'Y', 'IBLOCK_ID' => $ cntIBLOCK_List, 'IBLOCK_SECTION_ID' => $ item ['ID']);
            $ arSelect = array ('ID', 'NAME', 'DETAIL_PAGE_URL', 'PREVIEW_TEXT');

            $ res = CIBlockElement :: getList ($ arSort, $ arFilter, false, array (), $ arSelect);
            while ($ row = $ res-> fetch ()) {
                $ preferences [$ item ['ID']] ['ITEMS'] [] = $ row;
            }

        }

        //////////// end cache /////////
        if ($ cache_time> 0)
        {
            $ cache-> StartDataCache ($ cache_time, $ cache_id, $ cache_path);
            $ cache-> EndDataCache (array ("preferences" => $ preferences));
        }
    }

}
