有三个文件：
第一是:zcyh.php（注册用户名）

当前位置：主页>>注册页面

请设定用户名：（3-15位）

用户名：
注意：用户名只能由英文字母（a-z），数字（0-9）和下划线（'_'、'-'、'.' ）构成，不能有空格，且必须以英文字母为开头。
例如：
√正确的例子：jocky、lin_xing、nh2001
×错误的例子：li kitty、ming:)、168kk
如果你已经填写好，请点“下一步”按钮；点“取消”按钮即取消您刚才的输入，重新开始。

        $result=@mysql_query("select * from user1 where name='$name'" ,$conn);
        if($result){
