Getting value from JSON PHP

Question

I am trying to get ID from this Json.

I have already tried many things such as:

• json_encode($array); and then trying to get value using
• $array->contact->id;
• $array['contact']['id]; BUT FAILED.

This is the response I get from active campaign API. I am using PHP, and the only issue I am facing is extracting ID from this Response.

How can I get contact --> id from the response? Can somebody help?

here's the code:`

{
  "fieldValues": [
    {
      "contact": "113",
      "field": "1",
