您应该查看

You should look at get_object_vars , as your properties are declared private you should call this inside the class and return its results.

请注意，对于像字符串这样的原始数据类型，它会很好用，但我不知道它在嵌套对象中的表现.

Be careful, for primitive data types like strings it will work great, but I don't know how it behaves with nested objects.

在您的情况下，您必须执行类似操作；

in your case you have to do something like;

<?php
   print_r(get_object_vars($response->response->docs));
?>
