How to get the value of an element property - bitrix?

Question

1C-Bitrix

I track the property change event. I get an array in this form:

I insert the necessary data like this: For some fields, for some reason, some kind of array identifier is generated for each IB element:
$arFields['PROPERTY_VALUES']['71']['0']['VALUE']

$arFields['PROPERTY_VALUES']['75']['2878']['VALUE']

'2878' - dynamic array identifier
Why is this happening? Maybe I'm doing something wrong? How to proceed?

Answer 1

Solved the problem this way:
The solution is really ugly. Perhaps it was better to collect a good array and immediately display $arFields['PROPERTY_VALUES']['75']['VALUE']

Answer 2

Why is this happening?

This is the property value id from the b_iblock_element_property table
The essence of the task is not clear, you can track it in different ways for different purposes

Answer 3

Actually, what do you want to do?
