解析PHP对象中的xml数组响应

我正在开发一个UPS跟踪API，我调用了该API来跟踪包，我得到了正确的响应，但是在数组格式中，我对json解码还不熟悉，请告诉我如何在PHP中解析它，我必须在PHP中创建多个对象吗？我附加了输出以及PHP代码

PHP代码

if (isset($_POST['af0'])) {
    if (preg_match('/^[a-z\d_]{4,80}$/i', $_POST['trackingNumber'])) {
        $cleanTrackingNumber = $_POST['trackingNumber'];
        $someArray = upsTrack("$cleanTrackingNumber");
        echo '<pre>'; print_r($someArray); echo '</pre>';

    } else {
        echo 'Invalid tracking number... sigh...';
    }
}

如果您已经有了数组格式的输出，那么您就没有更多的json解码了

您可以使用$someArray从数组中获取任何数据。 这取决于您是否只想显示或保存它，例如在数据库中

你想完成什么？
