if(!G5_USE_CACHE || $cache_fwrite) {        $list = array();         $sql = " select * from {$g5['board_table']} where bo_table = '{$bo_table}' ";        $board = sql_fetch($sql);        $bo_subject = get_text($board['bo_subject']);				$sql = " select * from {$g5['member_table']} where mb_1 = '{$member['mb_1']}' and mb_id = '{$mb['mb_id']}' ";		$result = sql_query($sql);		$row = sql_fetch_array($result);				        $tmp_write_table = $g5['write_prefix'] . $bo_table; // 게시판 테이블 전체이름        $sql = " select * from {$tmp_write_table} where mb_id = '{$row['mb_id']}' and wr_is_comment = 0 order by wr_num limit 0, {$rows} ";         $result = sql_query($sql);        for ($i=0; $row = sql_fetch_array($result); $i++) {            $list[$i] = get_list($row, $board, $latest_skin_url, $subject_len);        }
