代码如下:
- <?php
- //打开用于存储留言的XML文件
- $guestbook = simplexml_load_file('DB/guestbook.xml');
- foreach($guestbook->thread as $th) //循环读取XML数据中的每一个thread标签
- {
- echo "<B>标题：</B>".$th->title."<BR>";
- echo "<B>作者：</B>".$th->author."<BR>";
- echo "<B>内容：</B><PRE>".$th->content."</PRE>";
- echo "<HR>";
- }
- ?>
代码如下:
- <?php
- $guestbook = new DomDocument(); //创建一个新的DOM对象
- $guestbook->load('DB/guestbook.xml'); //读取XML数据
- $threads = $guestbook->documentElement; //获得XML结构的根
- //创建一个新thread节点
- $thread = $guestbook->createElement('thread');
- $threads->appendChild($thread);
- //在新的thread节点上创建title标签
- $title = $guestbook->createElement('title');
- $title->appendChild($guestbook->createTextNode($_POST['title']));
- $thread->appendChild($title);
- //在新的thread节点上创建author标签
- $author = $guestbook->createElement('author');
- $author->appendChild($guestbook->createTextNode($_POST['author']));
- $thread->appendChild($author);
- //在新的thread节点上创建content标签
- $content = $guestbook->createElement('content');
- $content->appendChild($guestbook->createTextNode($_POST['content']));
- $thread->appendChild($content);
- //将XML数据写入文件
- $fp = fopen("DB/guestbook.xml", "w");
- if(fwrite($fp, $guestbook->saveXML()))
- echo "留言提交成功";
- else
- echo "留言提交失败";
- fclose($fp);
- ?>
