帝国CMS生成sitemap实现代码分享

因为对帝国CMS的sitemap插件不太满意，所以自己写了个sitemap生成工具，在sitemap中放了首页链接、栏目页链接和内容页链接，然后生成XML文件并且提交到百度站长工具，本文中的代码是需要生动生成的，我自己是在Linux中用cron写的定时任务，每天固定时间生成一次，先这样吧~ 

<div>

代码如下:</div>
<div id="phpcode1">
 
<?php 
/*引用文件*/ 
require('e/class/connect.php'); 
require('e/class/db_sql.php'); 
require('e/data/dbcache/class.php'); /*建立数据库链接与实例化类*/ 
$link = db_connect(); 
$empire=new mysqlquery(); //header("Content-type:application/xml"); 
header("Content-type: text/html; charset=utf-8"); $operation = $_GET['operation']; 
$current_url = explode('/',$_SERVER['PHP_SELF']); 
$current_script_name = end($current_url); if($operation && $operation == "makexml") 
{ 
$xml = generate_sitemp_xml(); 
$result = save_xml('sitemap.xml',$xml); 
if($result) 
{ 
echo '生成成功，<a href="sitemap.xml">点此查看</a>'; 
} 
else 
{ 
echo '生成失败，<a href="'.$current_script_name.'">在来一次</a>！'; 
} 
} 
else 
{ 
echo '欢迎使用微笑的鱼Sitemap生成工具，请<a href="'.$current_script_name.'?operation=makexml">点此生成</a>！'; 
} 
//保存到文件 
function save_xml($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; 
} 
//生成Sitemap XML数据 
function generate_sitemp_xml() 
{ 
global $dbtbpre,$empire; 
$xml = ''; 
$xml .= '<?xml version="1.0" encoding="utf-8"?>' .PHP_EOL; 
$xml .= '<urlset>' .PHP_EOL; 
$xml .= generate_home_xml();//首页 
$xml .= generate_class_xml();//栏目 
$query="select * from {$dbtbpre}ecms_news order by id desc limit 100"; 
$sql=$empire->query($query); 
while($r=$empire->fetch($sql)) 
{ 
$titleurl=sys_ReturnBqTitleLink($r); 
$xml .= ' <url>' .PHP_EOL; 
$xml .= ' <loc>'.$titleurl.'</loc>' .PHP_EOL; 
$xml .= ' <lastmod>'.strftime('%Y-%m-%d',$r['newstime']).'</lastmod>' .PHP_EOL; 
$xml .= ' <changefreq>daily</changefreq>' .PHP_EOL; 
$xml .= ' <priority>0.8</priority>' .PHP_EOL; 
$xml .= ' </url>' .PHP_EOL; 
} 
$xml .= '</urlset>' .PHP_EOL; 
return $xml; 
} 
//生成栏目链接XML数据 
function generate_class_xml() 
{ 
global $dbtbpre,$empire,$class_r; 
$xml = ''; 
$sql=$empire->query("SELECT * FROM {$dbtbpre}enewsclass WHERE islast=1"); 
while($r=$empire->fetch($sql)) 
{ 
$infor=$empire->fetch1("SELECT newstime FROM {$dbtbpre}ecms_".$class_r[$r]." WHERE classid='$r' ORDER BY newstime DESC LIMIT 1"); 
$class_url=sys_ReturnBqClassname($r, 9); 
$xml .= ' <url>' .PHP_EOL; 
$xml .= ' <loc>'.$class_url.'</loc>' .PHP_EOL; 
$xml .= ' <lastmod>'.strftime('%Y-%m-%d',time()).'</lastmod>' .PHP_EOL; 
$xml .= ' <changefreq>daily</changefreq>' .PHP_EOL; 
$xml .= ' <priority>0.8</priority>' .PHP_EOL; 
$xml .= ' </url>' .PHP_EOL; 
} 
return $xml; 
} 
//生成栏目链接XML数据 
function generate_home_xml() 
{ 
$xml = ''; 
$xml .= ' <url>' .PHP_EOL; 
$xml .= ' <loc>https://www.jb51.net</loc>' .PHP_EOL; 
$xml .= ' <lastmod>'.strftime('%Y-%m-%d',time()).'</lastmod>' .PHP_EOL; 
$xml .= ' <changefreq>daily</changefreq>' .PHP_EOL; 
$xml .= ' <priority>0.8</priority>' .PHP_EOL; 
$xml .= ' </url>' .PHP_EOL; 
return $xml; } /*关闭数据库连接与释放类*/ 
db_close(); 
$empire=null; 
?></div>
