xml加个节点怎么写
xml 结构如下







php如下
$note  = simplexml_load_file("a.xml");
$note->appendChild(new DOMElement("time","aaa"));


------解决方案--------------------
PHP在处理XML上有很多扩展,你的代码使用了simplexml类,也使用了DOMElement类,这两个类属于不同的扩展,所以不能用在一起。

提供一个simplexml的示例
$note  = simplexml_load_file("a.xml");<br />
$note->addChild("time","aaa");<br />
file_put_contents('a.xml', $note->asXML());
Copy after login
