用PHP处理SimpleXML元素

对此不熟悉，无法理解如何引用元素

我正在使用PHP，希望能够将First_Name中的值放入HTML表的单元格中

谢谢你的帮助

小部分输出：

SimpleXMLElement Object
(
[@attributes] => Array
    (
        [organization_KEY] => 5728
    )

[supporter-supporter_KEY-supporter_groups] => SimpleXMLElement Object
    (
        [item] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [supporter_KEY] => 6147839
                        [organization_KEY] => 12345
                        [chapter_KEY] => SimpleXMLElement Object
                            (
                            )

                        [Last_Modified] => Thu Jul 09 2009 15:11:39 GMT-0400 (EDT)
                        [Date_Created] => Thu Jul 09 2009 14:44:22 GMT-0400 (EDT)
                        [Title] => Mr.
                        [First_Name] => Michael

curl_setopt($ch, CURLOPT_URL, "$url/getLeftJoin.sjs");
$fields = array('object' => 'supporter(supporter_KEY)supporter_groups',       'condition'=>'supporter_KEY=123456' );

curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($fields));
// $output contains the output string
$output = curl_exec($ch);
//Populate results from salsa into SimpleXML object

$data = simplexml_load_string($output);
**echo ("data ". $data->supporter->First_Name);**

项是一个数组，因此可以寻址数组中的第一个元素：

$data->supporter->item[0]->名字

尝试：

echo$data->{'supporter-supporter\u KEY-supporter\u groups'}->item->[0]->First\u Name

大括号可以防止连字符被用作减法运算。

稍微调整一下。。echo$data->{'supporter-supporter\u KEY-supporter\u groups'}->item->First\u Name
