帝国cms怎么调用发布于10秒前 1周前 1个月前函数方法

function user_ago($tm,$rcs = 0) {
   $cur_tm = time(); $dif = $cur_tm-$tm;
   $pds = array('秒','分钟','小时','天','周','个月','年');
   $lngh = array(1,60,3600,86400,604800,2630880,31570560);
   for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]);

   $no = floor($no);
   //if($no <> 1) $pds[$v] .='s'; //+s
   $x=sprintf("%d %s",$no,$pds[$v]);
   if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0)) $x .= time_ago($_tm);
   return $x."前";
}

<?=user_ago($navinfor[newstime])?>

$listtemp = "发布时间".user_ago($r[newstime])."";
