예) 사이트의 모든글에서 특정기간설정하여 베스트글 출력하기
 --> http://www.sksna.com  좌측 하단스킨에 적용.

구현은 여러가지가 있으나..  속도를 고려해야 하기때문에 최종적으로 아래와 같은 방식으로 하였습니다.

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

1. db sql  추가.
----------------
-- 2007.12.16  모든 테이블 게시글 관리 추가

--
-- 테이블 구조 `g4_site_count`
--

DROP TABLE IF EXISTS `g4_site_count`;
CREATE TABLE `g4_site_count` (
  `bn_id` int(11) NOT NULL auto_increment,
  `bo_table` varchar(20) NOT NULL default '',
  `wr_id` int(11) NOT NULL default '0',
  `wr_parent` int(11) NOT NULL default '0',
  `bn_datetime` datetime NOT NULL default '0000-00-00 00:00:00',
  `mb_id` varchar(20) NOT NULL default '',
  `wr_subject` varchar(255) NOT NULL default '',
  `wr_content` text NOT NULL,
  `wr_hit` int(11) NOT NULL default '0',
  `ne_1` varchar(255) NOT NULL default '',
  `ne_2` varchar(255) NOT NULL default '',
  `ne_3` varchar(255) NOT NULL default '',
  `ne_4` varchar(255) NOT NULL default '',
  `ne_5` varchar(255) NOT NULL default '',
  `ne_6` varchar(255) NOT NULL default '',
  `ne_7` varchar(255) NOT NULL default '',
  `ne_8` varchar(255) NOT NULL default '',
  `ne_9` varchar(255) NOT NULL default '',
  `ne_10` varchar(255) NOT NULL default '',
  PRIMARY KEY  (`bn_id`),
  KEY `mb_id` (`mb_id`)
) ;

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

2. g4/config.php  중간에 아래 코드 추가
$g4['site_count']            = "g4_site_count";  //모든글 관리 테이블


3. g4/write_update.php   변경.  ( 소스참고 )

4. g4/delete.php  변경  (소스참고)

5. g4/delete_all.php 변경 (소스참고)

6. g4/board.php 152 라인에 히트 추가. (소스참고)
---------------------------
        //$g4['site_count']
        sql_query(" update $g4[site_count]  set wr_hit = wr_hit + 1 where wr_id = '$wr_id' and bo_table='$bo_table' ");
---------------------------

7. g4/bbs/count_hit.php  최신글 축출스킨 예시.
------------------------------------
