How to display a multiple property in Bitrix via API?

Question

API

Hello! Bitrix has a multiple property of the list type with the following parameters:

Here is the code by which I display this property:

<?require($_SERVER["DOCUMENT_ROOT"]."/bitrix/header.php");

$iblock_id  = 2;
$section_id = 34;

$arSelect = Array(
  "ID", 
  "NAME",
  "PROPERTY_ACTION");

$arFilter = Array( "IBLOCK_ID"=>$iblock_id, "SECTION_ID"=>$section_id, "ACTIVE_DATE"=>"Y", "ACTIVE"=>"Y" );
$res = CIBlockElement::GetList(Array("SORT"=>"ASC"), $arFilter, false, false, $arSelect);

while($ob = $res->GetNextElement()) :
  $arFields = $ob->GetFields();
  echo $arFields['PROPERTY_ACTION_VALUE'] . '<hr>';
endwhile;

require($_SERVER["DOCUMENT_ROOT"]."/bitrix/footer.php");?>

The output is this:

There are 7 products in this section, and only one product with a value filled in. This product has all the values.
It is displayed strangely, that is, with each pass of the loop, it displays one value of this multiple property.
How to get it out right?

Answer 1

this code will be inside your cycle, this is Bitrix, alas and ah

$VALUES = array();
$res = CIBlockElement::GetProperty($IBLOCK_ID, $ELEMENT_ID, Array("sort"=>"asc"), array("CODE" => "UF_NOTE_USER"));
    while ($ob = $res->GetNext())
    {
        $VALUES[] = $ob['VALUE'];
    }
}

Or another variant - if you include the plural in arSelect, then you will have such a nuance, it is described in the docks:
I do this - I include the multiple in arselect, but then in php I cut off the repetitions, the values ​​​​of the multiple fields that are the first by sorting will remain in the array.
This is Bitrix, baby, this is Bitrix.
