PHP后台最基本的注册代码： 
<body>
<?php
$name = $_REQUEST['name'];
$password = $_REQUEST['password'];
$intro = $_REQUEST['intro'];
mysql_connect('localhost','root','123');
mysql_select_db('te');
$sql = "insert into users(name,password,intro) value('$name','$password','$intro')";
mysql_query($sql);
if(mysql_affected_rows()>=1){
$_SESSION['name']=$name;
?>
<h1><span class="STYLE1">恭喜你! </span>你已成功注册！</h1>
<?php }?>
<?php mysql_close();?>
<a href="login.html">Go to 登陆
</a>
</body>
我也在复习ing....嘿嘿
