經典帝國CMS產生sitemap實作程式碼分享

因為對帝國CMS的sitemap插件不太滿意，所以自己寫了個sitemap生成工具，在sitemap中放了首頁鏈接、欄目頁鏈接和內容頁鏈接，然後生成XML檔案並且提交到百度站長工具，本文中的程式碼是需要生動生成的，我自己是在Linux中用cron寫的定時任務，每天固定時間生成一次，先這樣吧~

程式碼如下:

<?php
/*引用文件*/
require(&#39;e/class/connect.php&#39;);
require(&#39;e/class/db_sql.php&#39;);
require(&#39;e/data/dbcache/class.php&#39;);</p> <p>/*建立数据库链接 与 实例化类*/
$link = db_connect();
$empire=new mysqlquery(); </p> <p>//header("Content-type:application/xml");
header("Content-type: text/html; charset=utf-8");</p> <p>$operation = $_GET[&#39;operation&#39;];
$current_url = explode(&#39;/&#39;,$_SERVER[&#39;PHP_SELF&#39;]);
$current_script_name = end($current_url); </p> <p>if($operation && $operation == "makexml")
{
$xml = generate_sitemp_xml();
$result = save_xml(&#39;sitemap.xml&#39;,$xml);
if($result)
{
echo &#39;生成成功，<a href="sitemap.xml">点此查看</a>&#39;;
}
else
{
echo &#39;生成失败，<a href="&#39;.$current_script_name.&#39;">在来一次</a>！&#39;;
}
}
else
{
echo &#39;欢迎使用微笑的鱼Sitemap生成工具，请<a href="&#39;.$current_script_name.&#39;?operation=makexml">点此生成</a>！&#39;;
}</p> <p></p> <p>
//保存到文件
function save_xml($filename, $text) {
if (!$filename || !$text)
return false;

@chmod($filename,0777);
if ($fp = fopen($filename, "w")) {
if (@fwrite($fp, $text)) {
fclose($fp);
return true;
} else {
fclose($fp);
return false;
}
}
return false;
