print_r($result);
上面的代码返回了一个错误，“为foreach（）提供的参数无效”。我四处搜索，但仍然没有找到解决方案。它给了您该错误，因为
outboundOptionsforeach ($json2['outboundOptions'][0]['flights']as $theentity) {
$result[] = $theentity['flightNumber'];
}
]，jsonjson根据您的评论进行更新 要获取所有航班，请将foreach循环更改为：
foreach ($json3['outboundOptions'] as $flight) {
foreach($flight['flights'] as $theentity) {
$result[] = $theentity['flightNumber'];
}
}
['flights'][0]$json2=json\u decode（$json，TRUE）；
$result=array（）；
foreach（$json2['outboundOptions'][0]['flights']作为$theentity）{
$result[]=$theentity['flightNumber']；
}
打印（结果）它仍然返回相同的错误。我已经上传了完整的json。@maxcheng我可以问一下为什么要将它包装在
fn（）str_replace（array（“fn（，“}）”），“”，$json）然后解码。谢谢。它工作了。现在我可以从json获取航班号了。但是如果json包含超过1个航班号，我只能获得1个航班号。工作示例：
