作者：
百度目前还没有开放站点地图数据提交，但可以通过，百度站长工具的开放适配提交更新数据,大家参考使用吧
复制代码 代码如下:
function sitemapxml(){
$user = M('sethouse');//thinkphp 数据链接
$today = date("Y-m-d",time());
$yesterday = mktime(0, 0, 0, date("m") , date("d")-1, date("Y"));
$lastweek = strtotime("-1 week");
$link = M();
$yesterdayArr = $link->query("select * from pre_sethouse where status=1 and time>$yesterday");//昨天
$lastweekArr = $link->query("select * from pre_sethouse where status=1 and time>$lastweek");//上周
$url = "http://www.xxx.com/House/housecontent/id/";
foreach($yesterdayArr as $k=>$v){
$data_array[$k]['loc'] = $url.$v['hid'];
$data_array[$k]['lastmod'] = $today;
$data_array[$k]['changefreq'] = 'always';
$data_array[$k]['priority'] = '0.6';
$data_array[$k]['data'] = '<display></display>';
}
$content='<?xml version="1.0" encoding="UTF-8"?><urlset>'.chr(13).'';
$content.='<url>
<loc>http://www.xxx.com</loc>
<lastmod>'.$today.'</lastmod>
<changefreq>always</changefreq>
<priority>0.9</priority>
<data><display></display></data>
</url>'.chr(13);
foreach($data_array as $data){
$content.=create_item($data);
}
$content.='</urlset>';
$fp=fopen('sitemap.xml','w+');
fwrite($fp,$content);
fclose($fp);
}
function create_item($data){
$item="<url>\n";
$item.="<loc>".$data['loc']."</loc>\n";
$item.="<lastmod>".$data['lastmod']."</lastmod>\n";
$item.="<changefreq>".$data['changefreq']."</changefreq>\n";
$item.="<priority>".$data['priority']."</priority>\n";
$item.="<data>".$data['data']."</data>\n";
