【问题标题】:Pulling Array from PHP SimpleXMLElement从 PHP SimpleXMLElement 中提取数组
【发布时间】:2019-02-18 15:28:21
【问题描述】:

我想从 PHP SimpleXmlElement 中提取一个数组。 原始 SimpleXMLElement 的结构如下:

object(SimpleXMLElement)[226]
  public 'GetLeadDetailResponse' => 
    object(SimpleXMLElement)[239]
      public 'GetLeadDetailResult' => 
        object(SimpleXMLElement)[240]
          public 'LeadStat' => 
            array (size=4294)

xmlElement 存储在一个名为 $parser 的变量中,我想一直到“LeadStat”,所以我用以下方式编制索引:

$leadStatInfo = $parser->GetLeadDetailResponse->GetLeadDetailResult;

返回这个对象:

object(SimpleXMLElement)[4534]
  public 'LeadStat' => 
    array (size=4294)
      0 => 
        object(SimpleXMLElement)[240]
          public 'AdvertiserName' => string 'Modn Grp' (length=12)
          public 'AdvertiserId' => string '4539234' (length=6)
          public 'Timestamp' => string '2017-08-14T15:23:28.91' (length=22)
          public 'Type' => string 'Conversation' (length=15)
          public 'VisitId' => string '1442535353670' (length=9)
          public 'Attempt' => string '0' (length=1)
          public 'AgentName' => string 'Jack A' (length=6)
          public 'CustomerName' => string 'John Harris' (length=11)
          public 'CustomerEmail' => string 'harris@modn.com' (length=25)
          public 'CustomerPhone' => 
            object(SimpleXMLElement)[4535]
              ...
          public 'CustomerAddress' => 
            object(SimpleXMLElement)[4536]
              ...
          public 'NumberOfMessages' => string '12' (length=2)
      1 => 
        object(SimpleXMLElement)[4533]
          public 'AdvertiserName' => string 'Modn Grp' (length=12)
          public 'AdvertiserId' => string '4539234' (length=6)
          public 'Timestamp' => string '2017-08-14T17:21:11.157' (length=23)
          public 'Type' => string 'Conversation' (length=15)
          public 'VisitId' => string '37836763725' (length=9)
          public 'Attempt' => string '0' (length=1)
          public 'CustomerAddress' => 
            object(SimpleXMLElement)[4536]
              ...
          public 'NumberOfMessages' => string '0' (length=1)
      more elements...

现在我想获取LeadStat 数组并对其进行json_encode,所以我尝试了以下方法:

json_encode($leadStatInfo->LeadStat)

不幸的是,这只返回了一个对象,而不是数组中的所有对象。

{
  "AdvertiserName":"Modn Grp",
  "AdvertiserId":"4539234",
  "Timestamp":"2017-08-14T15:23:28.91",
  "Type":"Conversation",
  "VisitId":"1442535353670",
  "Attempt":"0",
  "AgentName":"Jack A",
  "CustomerName":"John Harris",
  "CustomerEmail":"harris@modn.com",
  "CustomerPhone":{},
  "CustomerAddress":{},
  "NumberOfMessages":"12"
}

如何取出整个数组?

这是因为数组中的对象没有相同的属性吗?

    【解决方案1】:

    在 SimpleXML 中,$leadStatInfo->LeadStat 并不是真正的数组,而是一个可迭代的元素。要获取 LeadStat 中的所有项目,您需要对其进行迭代。

    $leadStatArray = array();
    foreach($leadStatInfo->LeadStat as $leadStat) {
        $leadStatArray[] = $leadStat;
    }
    json_encode($leadStatArray);

    • 啊,我明白了。我被假数组迷惑了。谢谢,我的应用程序现在可以正常运行了。
