我正在尝试解析以下响应：

SimpleXMLElement Object ( 
    [responseType] => SimpleXMLElement Object ( 
        [inputConceptName] => aspirin [inputKindName] => % ) 
    [groupConcepts] => SimpleXMLElement Object ( 
        [concept] => Array ( 
            [0] => SimpleXMLElement Object ( 
                [conceptName] => ASPIRIN 
                [conceptNui] => N0000145918 
                [conceptKind] => DRUG_KIND ) 
            [1] => SimpleXMLElement Object ( #
                [conceptName] => Aspirin 
                [conceptNui] => N0000006582 
                [conceptKind] => INGREDIENT_KIND ) 
) ) )

在 PHP 中。我将它存储为 curl 字符串：

$xml = simplexml_load_string($data);
print_r($xml);

如何将第一个对象的 conceptNui 作为 PHP 变量获取？

看一下文档，它给出了简单的例子来理解提取数据的友好语法：

http://www.php.net/manual/en/simplexml.examples-basic.php

在你的情况下，它可能是：

$xml->groupConcepts->concept[0]->conceptNui

因为你的结构是

SimpleXMLElement Object ( 
  [responseType] => SimpleXMLElement Object ( 
    [inputConceptName] => aspirin 
    [inputKindName] => % ) 
  [groupConcepts] => SimpleXMLElement Object ( 
    [concept] => Array ([0] => SimpleXMLElement Object ( 
                    [conceptName] => ASPIRIN 
                    [conceptNui] => N0000145918 
                    [conceptKind] => DRUG_KIND ) 
              [1] => SimpleXMLElement Object ( 
                    [conceptName] => Aspirin 
                    [conceptNui] => N0000006582 
                    [conceptKind] => INGREDIENT_KIND ) 
              )
          )
  )

   $conceptNui = $mainObj->groupConcepts->concept[0]->conceptNui;
