surfchen老师。您指的两处确实很对，我确实在那两个地方做过修改，还麻烦您把正确的帮我改一下好么？
php配置文件php.iniregister_globals=off==>register_globals=on要重启apache
-----------------------或在程序中把$REMOTE_ADDR 改成$_SERVER['REMOTE_ADDR'] 当你的php 版本>= 4.1
$HTTP_SERVER_VARS['REMOTE_ADDR'] php ver < 5.0
我的数据库是用mysql连的
可以用$REMOTE_ADDR
surfchen老师  改的就很正确，我刚刚调试通过了。
谢谢各位老师！！！！！！！！！！！！！！！！！
