How to extract key value from json response in PHP

Question

I am using the getResponse api to get subscriber updates. This is what prints aftervar_dump($result);

object(stdClass)#2 (1) {
  ["updated"]=>
  int(1)
}

How to extract / decode / encode the result to request a key: "update" and get its value: 1?

thank

Answer 1

    // json object.
    $ contents = '{"firstName": "John", "lastName": "Doe"}';

    // Option 1: through the use of an array.
    $ jsonArray = json_decode ($ contents, true);

    $ key = "firstName";

    $ firstName = $ jsonArray [$ key];


    // Option 2: through the use of an object.
    $ jsonObj = json_decode ($ contents);

    $firstName = $jsonObj->$key;
