我正在尝试从simplexml对象中提取一组数据。但是，我的代码返回一个通知，如：
Notice: Trying to get property of non-object in C:\wamp\www\Departeasy_php\xmlintegrate.php on line 19.
我注意到的是，在xml对象中嵌套了一个数组，这可能导致它抛出这样的错误。
我经常搜索以找到解决方案，但无济于事。
请帮忙。
这是simplexml对象的一部分：
SimpleXMLElement Object

这是我的代码：`

$onward_flights = $contents->{"onward-solutions"}->children();

我是php的新手。如果还有更好的方法可以做到这一点，请建议。
答案 0 :(得分：0)
经过进一步研究，我终于得到了预期的结果： - 显然，只需要进一步采取循环..
这是代码：
<?php
$contents= simplexml_load_file('xml/cleartrip.xml');
$onward_flights = $contents->{"onward-solutions"};
foreach ($onward_flights->solution as $onwardflights)
{
$flightno= $onwardflights->flights->flight->segments->segment->airline.'-'.$onwardflights->solution->flights->flight->segments->segment->{"flight-number"};
$airline= $flightno;
$depdate= substr($onwardflights->flights->flight->segments->segment->{"departure-date-time"},0,10);
$deptime= substr($onwardflights->flights->flight->segments->segment->{"departure-date-time"},11,8);
$arrdate= substr($onwardflights->flights->flight->segments->segment->{"arrival-date-time"},0,10);
$arrtime= substr($onwardflights->flights->flight->segments->segment->{"arrival-date-time"},11,8);
$duration= $onwardflights->flight->segments->segment->duration;
$stops= $onwardflights->flights->flight->segments->segment->stops;
$origin= substr(filter_input(INPUT_POST, "origin"), 0, 3);
$destination= substr(filter_input(INPUT_POST, "destination"), 0, 3);
$fare= $onwardflights->{"pricing-summary"}->{"total-fare"};
echo $key." ".$flightno." ".$depdate." ".$arrdate." ".$fare." ".$airline." ".$deptime." ".$arrtime." ".$duration." ".$stops." ".$origin." ".$destination."<br/>";
}
