Question

我正在尝试装运API。 API返回对象。但是当我尝试使用简单的foreach循环访问某个值时，它无法正常工作。我尝试了不同的方法，但一切都给了我一个空白页面。

以下是从API收到的回复。

stdClass Object
(
[ConsignmentTrackEvents_Details_NewResult] => stdClass Object
    (
        [ConsignmentTrack] => Array
            (
                [0] => stdClass Object
                    (
                        [ERROR] => 
                        [DOCKNO] => 888888
                        [TRANSIT_LOCATION] => Location, Location
                        [ACTIVITY] => Out For Delivery
                        [EVENTDATE] => 22 Jul 2016
                        [EVENTTIME] => 21:05:48
                        [NEXT_LOCATION] => Coimbatore
                        [TRACKING_CODE] => O
                    )

                [1] => stdClass Object
                    (
                        [ERROR] => 
                        [DOCKNO] => 888888
                        [TRANSIT_LOCATION] => Location, Location
                        [ACTIVITY] => Picked up and Booking processed 
                        [EVENTDATE] => 06 Jun 2016
                        [EVENTTIME] => 16:40:39
                        [NEXT_LOCATION] => 
                        [TRACKING_CODE] => B
                    )

            )

    )

)

然后我使用以下循环来访问值。

foreach($result['ConsignmentTrackEvents_Details_NewResult'] ['ConsignmentTrack'] as $res){

echo $res['DOCKNO'];

}

我在这里做错了吗？

Answer 1

数组和对象是不同的东西，您使用$array['key']访问数组条目，使用$object->key访问对象属性

foreach($result->ConsignmentTrackEvents_Details_NewResult->ConsignmentTrack as $res){
    echo $res->DOCKNO;
}

Answer 2

您可以使用foreach循环遍历主集合，然后向下钻取到其中包含的对象，该对象（反过来）包含您要查找的数据。

<?php
   // $result HERE IS THE MAIN DATA...
    foreach($result as $key=>$data){
        $trackResult    = $result['ConsignmentTrackEvents_Details_NewResult'];
        foreach($trackResult as $intKey=>$objData){
            $dockNo         = $objData->DOCKNO;
            $transit        = $objData->TRANSIT_LOCATION;
            $activity       = $objData->ACTIVITY;
            $eventDate      = $objData->EVENTDATE;
            $eventTime      = $objData->EVENTTIME;
            $nextLocation   = $objData->NEXT_LOCATION;
            $trackingCode   = $objData->TRACKING_CODE;

            echo $dockNo;

        }

    }

无法从PHP对象访问值
