本文實(shí)例講述了PHP實(shí)現(xiàn)動(dòng)態(tài)創(chuàng)建XML文檔的方法。分享給大家供大家參考，具體如下：
一. 代碼
conn.php
<?php
$id=mysql_connect("localhost","root","root") or die('數(shù)據(jù)庫(kù)連接失敗:' . mysql_error());
if(mysql_select_db("db_database26",$id))
echo "";
else
echo ('數(shù)據(jù)庫(kù)錯(cuò)誤' . mysql_error());
mysql_query("set names gb2312");
?>

<a
ref="rss.xml">查看rss.xml文件中的內(nèi)容</a>
