Прошу прощения, наверно всетаки вот так:
[CODE]
$ar_IBLOCK_TYPE_a = array("info_center_1","info_center_2","info_center_3");
$db_iblock_type = CIBlockType::GetList(Array());
while($ar_iblock_type = $db_iblock_type->Fetch()){
if($arIBType = CIBlockType::GetByIDLang($ar_iblock_type["ID"], LANG) && in_array($ar_iblock_type["ID"], $ar_IBLOCK_TYPE_a))
{
echo htmlspecialcharsex($arIBType["NAME"])."<br>";
}
}[/CODE]
