Accesing JSON response data via PHP - php

Question

I'm using the Paypal API PHP REST SDK. I got a response that looks like in JSON format but i'm unable to access the properties inside the object and array.
How do I access the "state" properties from this JSON response via PHP? The response is being wrapped by the object of Paypal\Api\Payment type. foreach looping returns NULL
var_dump($response) looks like below:
object(PayPal\Api\Payment)#8 (1) {

array(8) {

I tried json_decode($response) but it returned NULL so i assumed that this is already the correct JSON format.
I tried echo $response->id and it returns blank
I've also tried multiple variations of foreach ($response->id as $value) { var_dump($value); } which also returns nothing
Help!

Answer 1

If you use only json_decode($result) it will not convert entire objects into an array.
So simply use
$result=json_decode($result, true, 512);
It will convert all the objects into associative array recursively.
Try it. It works for me.

Answer 2

It turns out that this is not a standard JSON format. For some reason the Paypal API SDK return it in their own "json" format through this line
$ret->fromJson($json);
return $ret;
I just skipped that and return $json instead and it gives me the format that i can put into json_decode for further processing.
return $json;
That took me 1 full freaking day! Pff...

Answer 3

You can also use
$response->toJSON();
then you can use
$result = json_decode($response);
echo ($result->state);

Answer 4

Convert json to a string then store the content in an array (decode it with json_decode).
