PHP邮件发送验证功能第一步：建立数据库把下面数据库复制粘贴在一个记事本，然后在PHPMyAdmin创建一个新的数据库并导入下面数据。
– 表的结构 `registered_members`–CREATE TABLE `registered_members` (`id` int(4) NOT NULL auto_increment,`name` varchar(65) NOT NULL default ”,`email` varchar(65) NOT NULL default ”,`password` varchar(65) NOT NULL default ”,`country` varchar(65) NOT NULL default ”,PRIMARY KEY? (`id`)) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;–– 导出表中的数据 `registered_members`–– ——————————————————––– 表的结构 `temp_members_db`–CREATE TABLE `temp_members_db` (`confirm_code` varchar(65) NOT NULL default ”,`name` varchar(65) NOT NULL default ”,`email` varchar(65) NOT NULL default ”,`password` varchar(15) NOT NULL default ”,`country` varchar(65) NOT NULL default ”
) ENGINE=MyISAM DEFAULT CHARSET=latin1;–– 导出表中的数据 `temp_members_db`–第二步：建立数据库连接请把下面代码复制到你的文本编编译器里面，并命名：config.php php
mysql_connect(“$host”, “$username”, “$password”)or die(“cannot connect to server”);mysql_select_db(“$db_name”)or die(“cannot select DB”);?>第三步：注册页面请把下面代码复制到你的文本编辑器里面，并命名：signup.php注册用户名:邮箱:密码:国家:?第四步：数据插入到数据和邮件发送请把下面代码复制到你的文本编辑器里面，并命名：signup_ac.php php
$to=$email;// Your subject$subject=”Your confirmation link here”;// From$header=”from: your name”;// Your message$message=”Your Comfirmation link \r\n”;$message.=”Click on this link to activate your account \r\n”;$message.=”http://www.yourweb.com/confirmation.php?passkey=$confirm_code”;// send email$sentmail = mail($to,$subject,$message,$header);}// if not found else {echo “Not found your email in our database”;}// if your email succesfully sent if($sentmail){echo “Your Confirmation link Has Been Sent To Your Email Address.”;}else {echo “Cannot send Confirmation link to your e-mail address”;}?>第五步：验证请把下面代码复制到你的文本编辑器里面，并命名：confirmation.php php
if($count==1){$rows=mysql_fetch_array($result1);$name=$rows['name'];$email=$rows['email'];$password=$rows['password'];$country=$rows['country'];$tbl_name2=”registered_members”;// Insert data that retrieves from “temp_members_db” into table “registered_members”
$sql2=”INSERT INTO $tbl_name2(name, email, password, country)VALUES(‘$name’, ‘$email’, ‘$password’, ‘$country’)”;$result2=mysql_query($sql2);}// if not found passkey, display message “Wrong Confirmation code”
else {echo “Wrong Confirmation code”;}// if successfully moved data from table”temp_members_db” to table “registered_members” displays message “Your account has been activated” and don’t forget to delete confirmation code from table “temp_members_db”
if($result2){echo “Your account has been activated”;// Delete information of this user from table “temp_members_db” that has this passkey$sql3=”DELETE FROM $tbl_name1 WHERE confirm_code = ‘$passkey’”;$result3=mysql_query($sql3);}}?>
注意：
如果没有邮箱服务器的，会出现如下面提示之类的东西：Warning: mail() [function.mail]: Failed to connect to mailserver at “localhost” port 25, verify your “SMTP” and “smtp_port” setting in php.ini or use ini_set() in E:\wamp\www\mailverification\signup_ac.php?on line?39 Cannot send Confirmation link to your e-mail address不用慌，这说明你的数据已经被写进数据库了。
你可以用以下方法去通过验证：先复制这个URL到你的浏览器：http://www.
你的网站.com/confirmation.php?passkey=然后到你的数据库里面把confirm_code复制粘贴在passkey=后面，并回车，会出现提示的：Your account has been activated!恭喜你了!你的邮件验证系统就完成了！如果有什么问题的，欢迎随时留言，回以最快的速度解决你的问题。由于时间关系，英文就不做翻译了。
