Php 从json获取数据的问题

我已经能够从json访问信息，但我需要更具体的信息。我需要地址。我试过了，但看不出来。我可以得到名字，但当我试图得到地址，我没有得到结果。 下面是json的var_转储

现在，我可以将这个名称与我要查找的名称进行比较

$json = json_decode($data,true);
$firstName = strtoupper($firstName);
$lastName = strtoupper($lastName);
var_dump($json);
foreach($json['NPI'] as $key => $val){
//echo $key .'=>'. $val.'<br>';
foreach($val as $item => $info){
    //echo $item .'=>'.$data.'<br>';
    if($item == 'AuthorizedOfficialFirstName' && $info == $firstName){

        echo $firstName.' '.$lastName.'<br>';


     }
    }
  }
}

$json=json\u decode（$data，true）；
$firstName=strtoupper（$firstName）；
$lastName=strtoupper（$lastName）；
var_dump（$json）；
foreach（$json['NPI']作为$key=>$val）{
//回显$key.'=>'.$val.
'；
foreach（$val作为$item=>$info）{
//回显$item.'=>'.$data.
'；
如果（$item=='AuthorizedOfficialFirstName'&&&$info==$firstName）{
回显$firstName.'.$lastName.'
'；
}
}
}
}

当我这样做时，我没有得到任何结果。请帮忙

$json = json_decode($data,true);
$firstName = strtoupper($firstName);
$lastName = strtoupper($lastName);
var_dump($json);
 foreach($json['NPI'] as $key => $val){
//echo $key .'=>'. $val.'<br>';
foreach($val as $item => $info){
    //echo $item .'=>'.$data.'<br>';
    if($item == 'AuthorizedOfficialFirstName' && $info == $firstName){
        if($item == 'FirstLineMailingAddress'){
        echo $firstName.' '.$lastName.'<br>';
        echo $info.'<br>';
        //echo $json['NPI']['FirstLinePracticeLocationAddress'];
     }
    }
   }
}

$json=json\u decode（$data，true）；
$firstName=strtoupper（$firstName）；
$lastName=strtoupper（$lastName）；
var_dump（$json）；
foreach（$json['NPI']作为$key=>$val）{
//回显$key.'=>'.$val.
'；
foreach（$val作为$item=>$info）{
//回显$item.'=>'.$data.
'；
如果（$item=='AuthorizedOfficialFirstName'&&&$info==$firstName）{
如果（$item=='FirstLineMailingAddress'）{
回显$firstName.'.$lastName.'
'；
回显$info.“
”；
//echo$json['NPI']['FirstLinePracticeLocationAddress']；
}
}
}
}

你的问题就在这里

if($item == 'AuthorizedOfficialFirstName' && $info == $firstName){
    if($item == 'FirstLineMailingAddress'){

$item不能同时为

授权官方域名

以及

一线邮件地址

因此，为什么它没有回声。

你能把确切的json放在你的帖子上吗echo…。或任何您想要检查的内容！这是公开信息
