How to select several Bitrix infoblock elements by ID array?

Question

PHP

Good afternoon, faced with a simple problem for which I can not find a rational solution.
There is an element in which, using the 'Binding to elements in the form of a list' property, I specify which elements from another infoblock should be displayed in the future.
Example: For an element (from ib Portfolio) on the page, display what services were applied to this work. Each service is a link and the name of the linked element of the Services infoblock.
In the toga, I have an array with the ID of the attached elements, I need to get their name and page address.
Through CIBlockElement::GetList - arFilter is impossible, because ID can only contain a numeric value.
Do not use the same loop for each ID!?
With what component or code can this be implemented? The task is trivial.
Thank you.

Actually, arFilter array values ​​support arrays.

$arFilter = Array("IBLOCK_ID"=>1, "ID"=>array(1,2,3));
$res = CIBlockElement::GetList(Array(), $arFilter, false, false, array());
while($ob = $res->Fetch())
{
 
}
