我尝试使用php的json_encode函数和simplexml_load_file等函数将此响应转换为json。但是转换后的数据总是空的。如有任何帮助，我们将不胜感激。

更新：问题已在新版易趣PHP SDK中得到解决，该SDK 0.1.3他在BaseType中添加了一个新方法toArray（），它将响应转换为关联的数组。感谢戴维斯。链接到变更日志https://github.com/davidtsadler/ebay-sdk/blob/master/CHANGELOG.md#013---2015-06-20

试试这个http://goessner.net/download/prj/jsonxml/

请务必阅读xml.com O'Reilly网站上的随附文章http://www.xml.com/pub/a/2006/05/31/converting-between-xml-and-json.html，详细介绍了这些转换的问题，我想你会觉得很有启发性。奥主持这篇文章的事实应该表明Stefan的解决方案是有价值的。
