以下是在帝国CMS中实现按小时统计文章发布数的方法：

按照小时显示更新数量

用sql调用
6小时：<?=$empire->gettotal(select count(*) as total from {$dbtbpre}ecms_表 where newstime>UNIX_TIMESTAMP()-6*3600)?>
12小时：<?=$empire->gettotal(select count(*) as total from {$dbtbpre}ecms_表 where newstime>UNIX_TIMESTAMP()-12*3600)?>
24小时：<?=$empire->gettotal(select count(*) as total from {$dbtbpre}ecms_表 where newstime>UNIX_TIMESTAMP()-24*3600)?>
一个星期：<?=$empire->gettotal(select count(*) as total from {$dbtbpre}ecms_表 where newstime>UNIX_TIMESTAMP()-86400*7)?>
一个月：<?=$empire->gettotal(select count(*) as total from {$dbtbpre}ecms_表 where newstime>UNIX_TIMESTAMP()-86400*30)?>

灵动标签调用
6小时：[e:loop={'select count(*) as total from [!db.pre!]ecms_表 where newstime>UNIX_TIMESTAMP()-6*3600',0,24,0}]<?=$bqr[total]?>[/e:loop]
12小时：[e:loop={'select count(*) as total from [!db.pre!]ecms_表 where newstime>UNIX_TIMESTAMP()-12*3600',0,24,0}]<?=$bqr[total]?>[/e:loop]
24小时：[e:loop={'select count(*) as total from [!db.pre!]ecms_表 where newstime>UNIX_TIMESTAMP()-24*3600',0,24,0}]<?=$bqr[total]?>[/e:loop]
一个星期：[e:loop={'select count(*) as total from [!db.pre!]ecms_表 where newstime>UNIX_TIMESTAMP()-86400*7',0,24,0}]<?=$bqr[total]?>[/e:loop]
一个月：[e:loop={'select count(*) as total from [!db.pre!]ecms_表 where newstime>UNIX_TIMESTAMP()-86400*30',0,24,0}]<?=$bqr[total]?>[/e:loop]


12*3600即12小时
86400*7即7天
----------------------------------------------------------------------------------
统计昨天发表的文章数量
<?php
$beginYesterday=mktime(0,0,0,date('m'),date('d')-1,date('Y'));
$endYesterday=mktime(0,0,0,date('m'),date('d'),date('Y'))-1;
?>
[e:loop={select count(*) as total from [!db.pre!]ecms_news where newstime BETWEEN $beginYesterday and $endYesterday,1,24,0}]<?=$bqr[total]?>[/e:loop] 篇 </li>

----------------------------------------------------------------------------------

当前栏目本周更新：
<?=$empire->gettotal(select count(*) as total from {$dbtbpre}ecms_news where classid='$GLOBALS[navclassid]' and newstime  >UNIX_TIMESTAMP()-86400*7)?>

注释：按栏目统计一周发布文章数 加 classid='栏目id' 
      按当前栏目一周发布文章数 加 classid='$GLOBALS[navclassid]'
