PHP用户注册邮箱验证激活帐号示例
现在大部份网站都需要用户利用邮箱注册，然后再发帐号激活邮件到用户注册邮箱，用户点击链接就可以激活帐号了，下面我来介绍一下具体方法。
功能需求
PHP程序开发，用户在网站注册，需要用户通过邮件链接激活帐号，当用户注册后（用户信息写入数据库），没有登录邮箱激活帐号，规定24小时后自动删除没有激活帐号的用户信息，实现激活链接过期后，用户还可以使用该信息在网站注册
准备数据表
用户信息表中字段Email很重要，它可以用来验证用户、找回密码、甚至对网站方来说可以用来收集用户信息进行Email营销，以下是用户信息表t_user的表结构：
CREATE TABLE IF NOT EXISTS `t_user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `username` varchar(30) NOT NULL COMMENT '用户名', `password` varchar(32) NOT NULL COMMENT '密码', `email` varchar(30) NOT NULL COMMENT '邮箱', `token` varchar(50) NOT NULL COMMENT '帐号激活码', `token_exptime` int(10) NOT NULL COMMENT '激活码有效期', `status` tinyint(1) NOT NULL DEFAULT '0' COMMENT '状态,0-未激活,1-已激活', `regtime` int(10) NOT NULL COMMENT '注册时间', PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8;
HTML
在页面中放置一个注册表单，用户可以输入注册信息，包括用户名、密码和邮箱。
<form id="reg" action="register.php" method="post"> <p>用户名：<input type="text" class="input" name="username" id="user"></p> <p>密 码：<input type="password" class="input" name="password" id="pass"></p> <p>E-mail：<input type="text" class="input" name="email" id="email"></p> <p><input type="submit" class="btn" value="提交注册"></p> </form>
对于用户的输入要进行必要的前端验证，关于表单验证功能，建议您参考本站文章：实例讲解表单验证插件Validation的应用，本文对前端验证代码略过，另外其实页面中还应该有个要求用户重复输入密码的输入框，一时偷懒就此略过。
register.php
用户将注册信息提交到register.php进行处理。register.php需要完成写入数据和发送邮件两大功能。
首先包含必要的两个文件，connect.php和smtp.class.php，这两个文件在外面提供的下载包里有，欢迎下载。
include_once("connect.php");//连接数据库
include_once("smtp.class.php");//邮件发送类
然后我们要过滤用户提交的信息，并验证用户名是否存在（前端也可以验证）。
<?php
$username = stripslashes(trim($_POST['username']));
$query = mysql_query("select id from t_user where username='$username'");
$num = mysql_num_rows($query);
if ($num == 1) {
echo '用户名已存在，请换个其他的用户名';
exit;
}
?>接着我们将用户密码加密，构造激活识别码：
<?php
$password = md5(trim($_POST['password'])); //加密密码
$email = trim($_POST['email']); //邮箱
$regtime = time();
$token = md5($username . $password . $regtime); //创建用于激活识别码
$token_exptime = time() + 60 * 60 * 24; //过期时间为24小时后
$sql = "insert into `t_user` (`username`,`password`,`email`,`token`,`token_exptime`,`regtime`)
values ('$username','$password','$email','$token','$token_exptime','$regtime')";
mysql_query($sql);
?>上述代码中，$token即构造好的激活识别码，它是由用户名、密码和当前时间组成并md5加密得来的。$token_exptime用于设置激活链接URL的过期时间，用户在这个时间段内可以激活帐号，本例设置的是24小时内激活有效。最后将这些字段插入到数据表t_user中。
当数据插入成功后，调用邮件发送类将激活信息发送给用户注册的邮箱，注意将构造好的激活识别码组成一个完整的URL作为用户点击时的激活链接，以下是详细代码：
<?php
if (mysql_insert_id()) {
$smtpserver = ""; //SMTP服务器，如：smtp.163.com
$smtpserverport = 25; //SMTP服务器端口，一般为25
$smtpusermail = ""; //SMTP服务器的用户邮箱，如xxx@163.com
$smtpuser = ""; //SMTP服务器的用户帐号xxx@163.com
$smtppass = ""; //SMTP服务器的用户密码
$smtp = new Smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass); //实例化邮件类
$emailtype = "HTML"; //信件类型，文本:text；网页：HTML
$smtpemailto = $email; //接收邮件方，本例为注册用户的Email
$smtpemailfrom = $smtpusermail; //发送邮件方，如xxx@163.com
$emailsubject = "用户帐号激活"; //邮件标题
//邮件主体内容
$emailbody = "亲爱的" . $username . "：<br/>感谢您在我站注册了新帐号。<br/>请点击链接激活您的帐号。<br/>
<a href='/demo/register/active.php?verify=" . $token . "' target=
'_blank'>/demo/register/active.php?verify=" . $token . "</a><br/>
如果以上链接无法点击，请将它复制到你的浏览器地址栏中进入访问，该链接24小时内有效。";
//发送邮件
$rs = $smtp->sendmail($smtpemailto, $smtpemailfrom, $emailsubject, $emailbody, $emailtype);
if ($rs == 1) {
$msg = '恭喜您，注册成功！<br/>请登录到您的邮箱及时激活您的帐号！';
} else {
$msg = $rs;
}
}
echo $msg;
?>还有一个相当好用且强大的邮件发送类分享个大家：使用PHPMailer发送带附件并支持HTML内容的邮件，直接可以用哦。
active.php
如果不出意外，您注册帐号时填写的Email将收到一封helloweba发送的邮件，这个时候您直接点击激活链接，交由active.php处理。
active.php接收提交的链接信息，获取参数verify的值，即激活识别码。将它与数据表中的用户信息进行查询对比，如果有相应的数据集，判断是否过期，如果在有效期内则将对应的用户表中字段status设置1，即已激活，这样就完成了激活功能。
<?php
include_once ("connect.php"); //连接数据库
$verify = stripslashes(trim($_GET['verify']));
$nowtime = time();
$query = mysql_query("select id,token_exptime from t_user where status='0' and
`token`='$verify'");
$row = mysql_fetch_array($query);
if ($row) {
if ($nowtime > $row['token_exptime']) { //24hour
$msg = '您的激活有效期已过，请登录您的帐号重新发送激活邮件.';
} else {
mysql_query("update t_user set status=1 where id=" . $row['id']);
if (mysql_affected_rows($link) != 1) die(0);
$msg = '激活成功！';
}
} else {
$msg = 'error.';
}
echo $msg;
?>激活成功后，发现token字段并没有用处了，您可以清空。接下来我们会讲解用户找回密码的功能，也要用到邮箱验证，敬请关注。
最后附上邮箱smtp.class.php发送类
