How to output infoblock property to any file?

Question

1C-Bitrix

How can I correctly output the infoblock property, for example, to a newly created file in the root of the site /main-test.php
These options do not work:

<? echo $arResult['DISPLAY_PROPERTIES']['ATTRIBUTE']['DISPLAY_VALUE'];?>
<? echo $arResult['PROPERTIES']['ATTRIBUTE']['VALUE'];?>

<?=$arResult['DISPLAY_PROPERTIES']['ATTRIBUTE']['DISPLAY_VALUE'];?>
<?=$arResult['PROPERTIES']['ATTRIBUTE']['VALUE'];?>
