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)."";
