如何解决如何从PHP中包含多个对象的响应中提取字符串？
我有一个$response变量，它从Square API调用中提取响应。 var_dump($response)提供以下输出：
object(Square\Http\ApiResponse)#26 (8) {
["request":"Square\Http\ApiResponse":private]=>
object(Square\Http\HttpRequest)#15 (4) {

["errors":"Square\Http\ApiResponse":private]=>
array(0) {
}
["cursor":"Square\Http\ApiResponse":private]=>
NULL
}
但是，我只对该对象中的单个字符串感兴趣：
object(Square\Models\CreatePaymentResponse)#28 (2) {
["errors":"Square\Models\CreatePaymentResponse":private]=>
NULL
["payment":"Square\Models\CreatePaymentResponse":private]=>
object(Square\Models\Payment)#30 (28) {
["id":"Square\Models\Payment":private]=>
string(29) "7PVOoMjV8mUoSaGWKrX1F8VDyHDZY"
我没有太多处理对象和JSON的经验，并且我一直在进行的所有阅读和研究都无法处理类似的事情，因此，我在这里寻求专家的帮助。如何从整个响应中提取id字符串？
编辑：
每个评论和答案，这里是文档的链接：
https://developer.squareup.com/reference/square/payments-api/create-payment
以及我正在使用的代码部分：
// Initialize the Square client.
$client = new Square\SquareClient([
'accessToken' => $access_token,'environment' => getenv('ENVIRONMENT')
]);
$payments_api = $client->getPaymentsApi();
$create_payment_request = new CreatePaymentRequest($nonce,uniqid(),$money);
// The SDK throws an exception if a Connect endpoint responds with anything besides
// a 200-level HTTP code. This block catches any exceptions that occur from the request.
try {
$response = $payments_api->createPayment($create_payment_request);
// If there was an error with the request we will
// print them to the browser screen here
if ($response->isError()) {
echo 'Api response has Errors';
$errors = $response->getErrors();
echo '<ul>';
foreach ($errors as $error) {
echo '<li>❌ ' . $error->getDetail() . '</li>';
}
echo '</ul>';
exit();
}
echo '<pre>';
$resp_arr = (array)json_decode($response,true);
var_dump($response);
var_dump($resp_arr);
echo '<br>';
echo 'Payment ID:';
echo $response->result->errors->payment->id;
echo '</pre>';
} catch (Square\Exceptions\ApiException $e) {
echo 'Caught exception!<br/>';
echo('<strong>Response body:</strong><br/>');
echo '<pre>'; var_dump($e->getResponseBody()); echo '</pre>';
echo '<br/><strong>Context:</strong><br/>';
echo '<pre>'; var_dump($e->getContext()); echo '</pre>';
exit();
}
在此先感谢您的帮助！

解决方法
从Square开发者论坛获得帮助。我能够使用getBody()调用来提取json响应并将其解码为数组：
$resp_arr = $response->getBody() ;
$resp_dec = json_decode($resp_arr,true) ;
$pmtid = $resp_dec["payment"] ["id"] ;
您已经尝试过吗？
echo $response->result->errors->payment->id;
此外，如果您更熟悉使用对象上的 array ，则可以将true用作json_decode()的参数，如下所示：>
$response = (array)json_decode($response,true);
通过这种方式，您将获得一个数组而不是对象
编辑
没有注意到他们是私人的。使用私有对象属性，您仍有一些方法来获取它。
-
使用文档中提到的类来获取属性
-
您可以尝试数组转换，然后在数组中搜索。
代码：
class Visibility {
public $public = 'public';
protected $protected = 'protected';
private $private = 'private';
}
var_dump((array) new Visibility());
