用PHP尋址SimpleXML元素

Question

這個新手並不能找出如何引用元素。

我正在使用PHP，並希望能夠將First_Name中的值放入HTML表格中的單元格。

感謝您的任何幫助。

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

是一個數組，所以可以在陣列中尋址第一元件：

$ DATA-> supporter->項[0] - >將First_Name

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

嘗試：

echo $ data - > {'supporter-supporter_KEY-supporter_groups'} - > item - > [0] - > First_Name;

大括號阻止對用作減法的連字符的任何解釋。
