一个简单的类问题，哪位朋友帮忙看看

问题出在“更新用户信息函数”那一段，当我用
$myUser=new user(watcher);
$myUser->;updateUser("watcher","login_times",1);
进行更新的时候，不管怎么刷新页面，login_times字段的值始终是1，根本不变（本来应该是不断加1才对）

程序代码：

1. class user{
   
2. var $uid;
   
3. var $name;
   
4. var $passwd;
   
5. var $gender;
   
6. var $birth;
   
7. var $email;
   
8. var $qq;
   
9. var $login_ip;
   
10. var $reg_ip;
    
11. var $login_date;
    
12. var $reg_date;
    
13. var $login_times;
    
14. var $good;
    
15. var $ati_num;
    
16. var $ati_d_num;
    
17. var $online;
    
18. var $face;
    
19. 
    
20. function user($userName){ &//开始构造函数user
    
21. $query="select * from user where name = '$userName'";
    
22. $result=mysql_query($query);
    
23. $re=mysql_fetch_array($result);
    
24. //初始化变量
    
25. $this->;uid=$re["uid"];
    
26. $this->;name=$re["name"];
    
27. $this->;gender=$re["gender"];
    
28. $this->;birth=$re["birth"];
    
29. $this->;qq=$re["qq"];
    
30. $this->;email=$re["email"];
    
31. $this->;passwd=$re["passwd"];
    
32. $this->;login_ip=$re["login_ip"];
    
33. $this->;reg_ip=$re["reg_ip"];
    
34. $this->;login_times=$re["login_times"];
    
35. $this->;good=$re["good"];
    
36. $this->;ati_d_num=$re["ati_d_num"];
    
37. $this->;ati_num=$re["ati_num"];
    
38. $this->;face=$re["face"];
    
39. $this->;online=$re["online"];
    
40. $this->;login_date=$re["login_date"];
    
41. $this->;reg_date=$re["reg_date"];
    
42. //变量初始化完毕
    
43. }
    
44. //*******输出用户信息函数*********//
