復制代碼 代碼如下:
//打開用于存儲留言的XML文件
$guestbook = simplexml_load_file('DB/guestbook.xml');
foreach($guestbook->thread as $th) //循環(huán)讀取XML數(shù)據(jù)中的每一個thread標簽
{
echo "標題：".$th->title."
";
echo "作者：".$th->author."
";
echo "內(nèi)容：
".$th->content."";
echo "
";
}
?>
復制代碼 代碼如下:
$guestbook = new DomDocument(); //創(chuàng)建一個新的DOM對象
$guestbook->load('DB/guestbook.xml'); //讀取XML數(shù)據(jù)
$threads = $guestbook->documentElement; //獲得XML結(jié)構(gòu)的根
//創(chuàng)建一個新thread節(jié)點
$thread = $guestbook->createElement('thread');
$threads->appendChild($thread);
//在新的thread節(jié)點上創(chuàng)建title標簽
$title = $guestbook->createElement('title');
$title->appendChild($guestbook->createTextNode($_POST['title']));
$thread->appendChild($title);
//在新的thread節(jié)點上創(chuàng)建author標簽
$author = $guestbook->createElement('author');
$author->appendChild($guestbook->createTextNode($_POST['author']));
$thread->appendChild($author);
//在新的thread節(jié)點上創(chuàng)建content標簽
$content = $guestbook->createElement('content');
$content->appendChild($guestbook->createTextNode($_POST['content']));
$thread->appendChild($content);
//將XML數(shù)據(jù)寫入文件
$fp = fopen("DB/guestbook.xml", "w");
if(fwrite($fp, $guestbook->saveXML()))
echo "留言提交成功";
else
echo "留言提交失敗";
fclose($fp);
?>
