最近在琢磨微信的接口
遇到了一个小问题
假如有个变量的内容如下

$test= "<xml><ToUserName><![CDATA[11111111]]></ToUserName><FromUserName><![CDATA[11111111]]></FromUserName><CreateTime>1111</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[test]]></Content><MsgId>111111</MsgId></xml>";

$postObj = simplexml_load_string($test, 'SimpleXMLElement', LIBXML_NOCDATA);
用simplexml_load_string把xml读到变量以后
$postObj->addChild("id","123");
我增加了一个元素
现在该怎么再把变量里的内容恢复成xml格式呢?

回复讨论(解决方案)

你再写回去不就行了
$test = $postObj->saveXML();

不过请注意，你打开的时候有 LIBXML_NOCDATA 参数，所以写回的就没有 CDATA 节点了

犯糊涂了刚看了半天PHP SimpleXML 函数
一直以为是saveXml是把xml保存成文件....谢谢
