我是靠谱客的博主热心水池，最近开发中收集的这篇文章主要介绍用Php编写注册后Email激活验证的实例代码，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

总共需两个页面，register.php 和 verify.php

1. 用户注册表格 register.php

复制代码代码如下:

<html>

<body>

用户名：<input type="text" name="username" />

密码：<input type="password" name="password" />

电子邮件：<input type="text" name="email" />

</form>

</body>

</html>

2. 创建用户数据表格 Users

复制代码代码如下:

CREATE TABLE IF NOT EXISTS `users` (

`id` int(11) NOT NULL auto_increment,

`status` varchar(20) NOT NULL,

`username` varchar(20) NOT NULL,

`password` varchar(20) NOT NULL,

`email` varchar(20) NOT NULL,

`activationkey` varchar(100) NOT NULL,

PRIMARY KEY (`id`),

UNIQUE KEY `username` (`username`),

UNIQUE KEY `email` (`email`),

UNIQUE KEY `activationkey` (`activationkey`)

) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=9 ;

3. 创建验证码用户注册信息存入数据表
我们使用状态‘verify' 来表示尚未激活的用户。

复制代码代码如下:

$activationKey = mt_rand() . mt_rand() . mt_rand() . mt_rand() . mt_rand();

$username = mysql_real_escape_string($_POST[username]);

$password = mysql_real_escape_string($_POST[password]);

$email = mysql_real_escape_string($_POST[email]);

$sql="INSERT INTO users (username, password, email, activationkey, status) VALUES ('$username', '$password', '$email', '$activationKey', 'verify')";

4. 发送验证码

复制代码代码如下:

echo "An email has been sent to $_POST[email] with an activation key. Please check your mail to complete registration.";

##Send activation Email

$to = $_POST[email];

$subject = " YOURWEBSITE.com Registration";

$message = "Welcome to our website!\r\rYou, or someone using your email address, has completed registration at YOURWEBSITE.com. You can complete registration by clicking the following link:\rhttp://www.YOURWEBSITE.com/verify.php?$activationKey\r\rIf this is an error, ignore this email and you will be removed from our mailing list.\r\rRegards,\ YOURWEBSITE.com Team";

$headers = 'From: noreply@ YOURWEBSITE.com' . "\r\n" .

'Reply-To: noreply@ YOURWEBSITE.com' . "\r\n" .

'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);

5. 验证激活代码 verify.php
如果验证码相同，则激活用户。

复制代码代码如下:

$queryString = $_SERVER['QUERY_STRING'];

$query = "SELECT * FROM users";

$result = mysql_query($query) or die(mysql_error());

while($row = mysql_fetch_array($result)){

if ($queryString == $row["activationkey"]){

echo "Congratulations!" . $row["username"] . " is now the proud new owner of a YOURWEBSITE.com account.";
