一、代码
1、conn.php
<?php $conn = mysql_connect("localhost", "root", "111") or die("连接数据库服务器失败!".mysql_error()); //连接MySQL服务器 mysql_select_db("db_database21",$conn); //选择数据库db_database21 mysql_query("set names utf8"); //设置数据库编码格式utf8 ?>
2、index.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>用户注册</title> <style type="text/css"> <!-- body,td,th { font-size: 12px; } --> </style></head> <body> <form id="form1" name="form1" method="post" action="index_ok.php"> <fieldset style="width:500px"><legend style="font-size:16px">用户注册</legend><table width="300" border="0" align="center"> <tr> <td width="77" align="right">用户名:</td> <td width="213"><input name="user" type="text" id="user" size="24" /></td> </tr> <tr> <td align="right">密码:</td> <td><input name="pwd" type="password" id="pwd" size="25" /></td> </tr> <tr> <td> </td> <td><input type="submit" name="sub" value="注册" /> <input type="reset" name="res" value="重置" /></td> </tr> </table></fieldset> </form> </body> </html>
