关于 session 不能自动去除的临时处理方法
问题是：
"PHP 的 session 会一直保存着用户第一次进入时输入的信息，即使你返回到登陆画面重新登陆也不会改变！这个问题我在 php4.02 里面发现，在最新的php 4.03pl1 的测试中仍然没有通过！只有用户关闭 ie 浏览器，重新开 IE窗口才能消除session的内容
临时解决方法：
当表单提交后,不要注册表单提交的变量,把该变量赋给另一变量$X后,注册$X,这样返回到登陆画面重新登陆就可以改变了.再要保险一点,可在登陆的那一页的页首添一句删除变量$X.
举例如下：这段是我的聊天室登陆的部分
1 登陆页面传送 $name , $pass
2 login.php 里可以这样处理
$save_name = $name;
$save_pass = $pass;
session_start();
session_register("name");
session_register("pass");
$name=$save_name;
$pass=$save_pass;
......
