php分页求助。修改一个uchome插件。遇到分页问题

1. //后添加充值记录
   
2. $page = empty($_GET['page'])?1:intval($_GET['page']);
   
3. if($page<1) $page=1;
   
4. $comment_ul1 ='cp.php?ac=card&view=me';
   
5. $id = empty($_GET['id'])?0:intval($_GET['id']);
   
6. $perpage = 30; //每页要显示的条数
   
7. $start = ($page-1)*$perpage;
   
8. ckstart($start, $perpage);
   
9. $count = $_SGLOBAL['db']->result($_SGLOBAL['db']->query("SELECT * FROM ".tname('app_card')." where money=500 ORDER BY id DESC"),0);
   
10. 
    
11. $query = $_SGLOBAL['db']->query("SELECT * FROM ".tname('app_card')." where money=500 ORDER BY id DESC limit $start,$perpage ");
    
12. while ($row = $_SGLOBAL['db']->fetch_array($query))
    
13. {
    
14. $plist[] = $row;
    
15. }
    
16. $multi = multi($count, $perpage, $page, $comment_ul1);
    
17. //后添加充值记录
    
18. 
    
19. app_card 表里共有50记录 其中 money=500 有25 条 为什么我查出的 $count 是50 而不是25 怎么才能正确多好这个 $count

复制代码

09.$count = $_SGLOBAL['db']->result($_SGLOBAL['db']->query("SELECT * FROM ".tname('app_card')." where money=500 ORDER BY id DESC"),0);
?????
这里是要的统计数量，而不是查询的值~·~
$count = $_SGLOBAL['db']->result($_SGLOBAL['db']->query("SELECT count(*) FROM ".tname('app_card')." where money=500 "),0);

谢谢你哦。
