Accesing JSON response data via 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) {
  ["_propMap":"PayPal\Common\PPModel":private]=>
  array(8) {
    ["id"]=>
string(28) "PAY-8JC052XXXXKKZMQNQ"
["create_time"]=>
string(20) "2013-12-19T10:19:34Z"
["update_time"]=>
string(20) "2013-12-19T10:20:38Z"
["state"]=>
string(8) "approved"
["intent"]=>
string(4) "sale"
["payer"]=>
object(PayPal\Api\Payer)#33 (1) {
  ["_propMap":"PayPal\Common\PPModel":private]=>
  array(2) {
    ["payment_method"]=>
    string(6) "paypal"
    ["payer_info"]=>
    object(PayPal\Api\PayerInfo)#30 (1) {
      ["_propMap":"PayPal\Common\PPModel":private]=>
      array(5) {
        ["email"]=>
        string(11) "[email protected]"

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!

Post your foreach loop & the json to object conversion code. Also I will suggest you to convert your json object to an array rather than an object. — Rikesh

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.

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...

You can also use

$response->toJSON();

then you can use

$result = json_decode($response);
echo ($result->state);

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

I tried to json_decode the response but it returns NULL. Is it because this is not a proper JSON format?
