当我试图从上面的json获得航班号时，它会给我一个错误。＆＃34;试图获得非对象的属性＆＃34;和＃34;为foreach（）＆＃34;提供的参数无效。
这是我的代码：
$flight = json_decode($result,true);
$info = $flight->outboundOptions->flights;
foreach ($info as $flightinfo){
echo $flightinfo['flightNumber'];
}
我知道这是错的，但我不确定我是否在正确的轨道上。
提前致谢。
答案 0 :(得分：0)
通过将true指定为json_decode()的第二个参数，您告诉它返回关联数组而不是对象，因此您可以将其取出以匹配当前代码。
另请注意$flight->outboundOptions是一个数组，因此您需要循环它或访问[0]索引才能到达->flights。
试试这个：
$flight = json_decode($result);
$info = $flight->outboundOptions[0]->flights;
foreach ($info as $flightinfo){
echo $flightinfo->flightNumber;
}
