如何打印 SimpleXMLElement 对象的特定数组元素

Question

我想从任何数组的响应中获取结果。这是数组输出：

    SimpleXMLElement Object
    (
       [GetCharitiesByKeywordResponse] => SimpleXMLElement Object
        (
            [GetCharitiesByKeywordResult] => SimpleXMLElement Object
            (
                [CharityList] => Array
                    (
                        [0] => SimpleXMLElement Object
                            (
                                [RegisteredCharityNumber] => 1175358
                                [SubsidiaryNumber] => 0
                                [CharityName] =>  LYDIARD PARK HERITAGE TRUST                                                                                                                          
                                [MainCharityName] =>  LYDIARD PARK HERITAGE TRUST                                                                                                                          
                                [RegistrationStatus] => Registered
                                [PublicEmailAddress] => info@lydiardtrust.org.uk
                                [MainPhoneNumber] => 07763059645
                            )

                        [1] => SimpleXMLElement Object
                            (
                                [RegisteredCharityNumber] => 1188662
                                [SubsidiaryNumber] => 0
                                [CharityName] =>  PALACE THEATRE & OPERA HOUSE TRUST                                                                                                                   
                                [MainCharityName] =>  PALACE THEATRE & OPERA HOUSE TRUST                                                                                                                   
                                [RegistrationStatus] => Registered
                                [PublicEmailAddress] => SheenaWrigley@theambassadors.com
                                [MainPhoneNumber] => 01612456636
                            )

我试图通过以下代码打印第一个元素的 'Charity Name'，但我得到的是空值：

print "<br>Result = ". $parser['GetCharitiesByKeywordResponse']['GetCharitiesByKeywordResult']['CharityList']['0']['CharityName'];

需要帮助才能打印出来。

谢谢

是对象，不是数组。

试试这个：

$parser->GetCharitiesByKeywordResponse->GetCharitiesByKeywordResult->CharityList[0]->CharityName;
