有关取一个obj的值

Jun 06, 2016 pm 08:43 PM
jsonobject php

有一物件如下:(xml格式)
[altLineId] => SimpleXMLElement Object
(
[0] => 651382441
)

前面略,都可取到,但这个难倒我了。
对象下有一个数组里面有一个元素key值叫 altLineId
现在我要取出 这个 651382441

已试方式如下

<code>$a=$tmp1['altLineId']=$spreadV['altLineId'][0]; //空白 
$a=$tmp1['altLineId']=$spreadV['altLineId']->0; //错误
$a=$tmp1['altLineId']=$spreadV['altLineId']->[0]; //错误
$a=$tmp1['altLineId']=$spreadV['altLineId']->'0' //错误
$a=$tmp1['altLineId']=$spreadV['altLineId']->['0'] //错误
</code>
Copy after login
Copy after login

求大大解!

$a = $tmp1['altLineId'] = $spreadV['altLineId']->{0}; 
Copy after login

我记得如果是SimpleXML解析的话直接用 $spreadV->altLineId 就可以获取到第一个值了吧,如果是多个的话就用foreach($spreadV->altLineId as $lineId){}好了。而且有点想吐槽你的标签,明明是XML解析结果给了一个JSONObject的标签。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM
