Accessing JSON objects via PHP

Question

I'm getting response from an API as JSON object, below is the JSON object that I am getting. I am trying to access some fields from it, but somehow, it is not working.

I am very new to API and JSON, so any help will be great.

{
  [
    "result"
  ]=>object(stdClass)#5(17){
    [
      "id"
    ]=>string(32)"f3add916cd34d635cb88452f4b024028"[

How do I access the ID variable within "result" or both the nameservers?

I've tried this, doesn't work.

foreach($a as $b=>$c)
    {
        echo $b . "=" . $c;
        echo "<br>";
    }

$a contains the json object. Please guide me right direction.
