PHP getting values in multidimensional array

In php how would I get the value 'error' in this array below? I did a var_dump($myArray);

I tried echo $myArray[0][0]; and $myArray[0]; but neither of these worked.

array(1) {
      [0]=>
      array(1) {
        ["error"]=>
        array(4) {
          ["message"]=>
          string(27) "Invalid OAuth access token."
          ["type"]=>
          string(14) "OAuthException"
          ["code"]=>
          int(190)
          ["fbtrace_id"]=>
          string(11) "GJb4ZZLyAll"
        }
      }
    }

What I am actually looking for is to check the value of $myArray[0][0]; If my code works that value will be "id". If it didn't work it will be "error". So I need to see if it says "id" or "error".

As from my understanding you want to check the value of the key. So we get the keys as an array with array_keys(), with this you then can access the first key and check if it is id or error, e.g.

$keys = array_keys($myArray[0]);

if($keys[0] == "id") {
    //good
} elseif($keys[0] == "error") {
    //bad
}

In PHP you can access array elements by name. So to get the value of "error" type:

$value = $myArray[0]["error"];
