有三个文件：
第一是:zcyh.php（注册用户名）<?include("header1.inc.php")?>
<div align=center>
<table width="89%" border="0">
    <tr>  
      <td><font color="#ff0000">当前位置：<a href="index.php">主页</a>&gt;&gt;注册页面</font></td>
    </tr>
  </table><br>

  <table width="82%" border="0" height="27">
    <tr>  
      <td height="14"><b><font color="#660099"><img src="images/dyb.gif" width="68" height="22">  
        请设定用户名：（<font color="#FF0000">3-15位</font>）</font></b></td>
    </tr>
  </table>
  <form name="form1" method="post" action="register.php">
    <table width="80%" border="0" height="154">
      <tr>  
        <td width="42%">  
          <div align="right"><font color="#0000FF">用户名：</font>
        </td>
        <td width="58%">  
          <input type="text" name="name" maxlength="20">
        </td></div>
      </tr>
      <tr>  
        <td colspan="2" height="27">  
          <div align="left"><font size="2"><font color="#FF0000">注意：</font><font color="#0000FF">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。 </font></font> </div>
        </td>
      </tr>
      <tr>  
        <td colspan="2" height="14">  
          <div align="left"><font size="2"><font color="#FF0000">例如：</font></font></div>
        </td>
      </tr>
      <tr>  
        <td colspan="2">

          <div align="center"><font size="2" color="#0000FF">如果你已经填写好，请点“</font><font size="2"><font color="#FF0000">下一步</font><font color="#0000FF">”按钮；  
            点“</font><font color="#FF0000">取消</font><font color="#0000FF">”按钮即取消您刚才的输入，重新开始。</font>  
            </font></div>
        </td>
      </tr>
      <tr>  
        <td colspan="2" height="19">  
          <div align="center">  
           
            <input type=image name=name2 src="images/xyb.gif" width="68" height="22" border="0">

        </td>
      </tr>
    </table>
  </form>
<br>
  
</div>
<br>
<?include("foot.inc.php")?>
</body>
</html>
第二个是：register.php(判断注册用户名是否正确和是否重复，然后输出注册的详细表单)
<?include("header1.inc.php")?>
<div align=center>
<table width="89%" border="0">
    <tr>  
      <td><font color="#ff0000">当前位置：<a href="index.php">主页</a>&gt;&gt;<a href=zcyh.php>注册页面</a>&gt;&gt;详细资料</font></td>
    </tr>
  </table><br>
<?
if($name==""){
    echo"<br><center><font color=blue>用户名不能为空。请</font><a href=zcyh.php>返回</a></center><br>";
    include("foot.inc.php");
    exit();
}
if(strlen($name)<3 || strlen($name)>15){
    echo"<br><center><font color=blue>用户名的长度不符合要求。请</font><a href=zcyh.php>返回</a></center><br>";
  include("foot.inc.php");
    exit();
}
if (!eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*$", $name)) {
       echo"<br><center><font color=blue>注册名只能由字母数字组成.请</font><a href=zcyh.php>返回</a></center><br>";
      include("foot.inc.php");
    exit();
    }
if ($name)
    {     
        $conn=@mysql_connect("localhost");
        $sql=@mysql_select_db("jocky",$conn);
        $result=@mysql_query("select * from user1 where name='$name'" ,$conn);
        if($result){
             if(@mysql_fetch_object($result)){
                 echo"<br><center><font color=blue>对不起，已经有相同的用户名！请</font><a href=zcyh.php>返回</a>.</center><br>";}
                 else{$conn=@mysql_connect("localhost");

                     @mysql_query($sqldo,$conn);
                 echo"<br><center><font color=blue>你好，</font>";
                 echo"<font color=red><b>$name</b></font></center>";

        }
    ?>
    </div>
<?include("foot.inc.php")?>
</body>
</html>
第三个是：check.php(判断注册资料是否正确，然后插入数据库，重新登录)
<?include("header1.inc.php")?>

      <td><font color="#ff0000">当前位置：<a href="index.php">主页</a>&gt;&gt;<a href=zcyh.php>注册页面</a>&gt;&gt;详细资料</font></td>
