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";     $item.="</url>n";     return $item; }
