通过PHP访问JSON响应数据 [英] Accesing JSON response data via PHP
问题描述
我正在使用Paypal API PHP REST SDK.我收到的响应看起来像是JSON格式，但是我无法访问对象和数组中的属性.
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.
如何通过PHP通过此JSON响应访问状态"属性?该响应由Paypal \ Api \ Payment类型的对象包装. foreach循环返回NULL
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)如下所示:
var_dump($response) looks like below:

我尝试了json_decode($ response)，但是它返回NULL，所以我认为这已经是正确的JSON格式.
I tried json_decode($response) but it returned NULL so i assumed that this is already the correct JSON format.
我尝试了echo $ response-> id并返回空白
I tried echo $response->id and it returns blank
我还尝试了foreach的多种变体($ response-> id作为$ value){var_dump($ value); }，也不会返回任何内容
I've also tried multiple variations of foreach ($response->id as $value) { var_dump($value); } which also returns nothing
帮助！
推荐答案
事实证明这不是标准的JSON格式.由于某种原因，Paypal API SDK通过此行以其自己的"json"格式返回它
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 $ret;
我只是跳过了它，而是返回$ json，它给了我可以放入json_decode进行进一步处理的格式.
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;
这让我花了整整一整天的时间！ PFF ...
That took me 1 full freaking day! Pff...
