调用方法getData()传入不同的参数可分别生成xml数据或json格式数据

 getData($data, '', 'json');  //返回json数据

{"result":"success","msg":"","info":{"data_info":[{"goods_id":"1","last_modify":"1423937979"},{"goods_id":"2","last_modify":"1425595831"},{"goods_id":"3","last_modify":"1423937959"},{"goods_id":"4","last_modify":"1423942862"}],"counts":"4"}}

 getData($data, '', 'xml');  //返回xml数据
