隔离php对象变量

Question

我将一些XML作为对象返回，如下所示：

SwitchvoxResponse Object
(
[apiStatus:private] => success
[apiErrors:private] => Array
    (
    )

[apiResult:private] => Array
    (
        [calls] => Array
            (
                [page_number] => 1
                [total_pages] => 1
                [items_per_page] => 50
                [total_items] => 1
                [call] => Array
                    (

                                                    )

                                                    )

                                                [2] => Array
                                                    (
                                                        [start_time] => 2011-06-17 13:41:02
                                                        [type] => TALKING
                                                        [display] => Talked to CALLEE_NAME <6534> for 43 seconds
                                                    )

                                                [3] => Array

                                                        [type] => HANGUP
                                                        [display] => Call was hung up by CALLER_NAME <4485>

                                            )

                                    )

                            )
                    )
            )
    )
)

如何提取这些变量的值？

Answer 1

可以通过SwitchvoxResponse::getResult()方法访问结果。鉴于$object是问题中引用的SwitchvoxResponse对象，下面的示例会循环遍历每个call并打印from值。

$result = $object->getResult();
foreach ($result['calls']['call'] as $call) {
    echo $call['from'];
}

同样，响应状态通过$object->getResponseStatus()获取，任何错误都来自$object->getErrors()。

回复状态可以是SV_RESPONSE_SUCCESS，SV_RESPONSE_FAULT或SV_RESPONSE_FAILED之一。

要获取第一个电话的项目，只需执行以下操作：

$result = $object->getResult();
$call = $result['calls']['call'][0];
// And access the values like
echo $call['from_name']; 

Answer 2

所有三个属性都标记为private，因此必须通过标记为public

的访问方法获取它们
