百度站点地图sitemap.xml生成代码

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。

1. function sitemapxml(){
2. $user = M('sethouse');//thinkphp 数据链接
3. $today = date("Y-m-d",time());
4. $yesterday = mktime(0, 0, 0, date("m") , date("d")-1, date("Y"));
5. $lastweek = strtotime("-1 week");
6. $link = M();
7. $yesterdayArr = $link->query("select * from pre_sethouse where status=1 and time>$yesterday");//昨天
8. $lastweekArr = $link->query("select * from pre_sethouse where status=1 and time>$lastweek");//上周
9. $url = "http://www.xxx.com/House/housecontent/id/";
10. foreach($yesterdayArr as $k=>$v){
11. $data_array[$k]['loc'] = $url.$v['hid'];
12. $data_array[$k]['lastmod'] = $today;
13. $data_array[$k]['changefreq'] = 'always';
14. $data_array[$k]['priority'] = '0.6';
15. $data_array[$k]['data'] = '';
16. }
17. $content=''.chr(13).'';
18. $content.='
19. http://www.xxx.com
20. '.$today.'
21. always
22. 0.9
'.chr(13);
25. foreach($data_array as $data){
26. $content.=create_item($data);
27. }
28. $content.='
';
29. $fp=fopen('sitemap.xml','w+');
30. fwrite($fp,$content);
31. fclose($fp);
32. }
33. function create_item($data){
34. $item="\n";
35. $item.="".$data['loc']."\n";
36. $item.="".$data['lastmod']."\n";
37. $item.="".$data['changefreq']."\n";
38. $item.="".$data['priority']."\n";
