注册后台处理，发送验证邮件需要下载Zend Framework

register_chk.php

<?php
    include_once 'conn/conn.php';
    require_once 'Zend/Mail.php';                        //调用发送邮件的文件
    require_once 'Zend/Mail/Transport/Smtp.php';        //调用SMTP验证文件
    $reback = '0';
    $url = 'http://'.$_SERVER['SERVER_NAME'].dirname($_SERVER['SCRIPT_NAME']).'/activation.php';
    $url .= '?name='.trim($_GET['name']).'&pwd='.md5(trim($_GET['pwd']));
    
    //发送激活邮件
    $subject="激活码的获取";
    $mailbody='注册成功。您的激活码是：'.'<a href="'.$url.'" target="_blank">'.$url.'</a><br>'.'请点击该地址，激活您的用户！';
//定义邮件内容
    $envelope="[email protected]";        //定义登录使用的邮箱

    $config = array('auth' => 'login',
            'username' => 'mrsoft8888',
            'password' => 'mrsoft8888');                //定义SMTP的验证参数
    $transport = new Zend_Mail_Transport_Smtp('smtp.sohu.com', $config);        //实例化验证的对象
    $mail = new Zend_Mail('GBK');            //实例化发送邮件对象
    $mail->setBodyHtml($mailbody);                //发送邮件主体
    $mail->setFrom($envelope, '明日科技典型模块程序测试邮箱，恭喜您用户注册成功！');    //定义邮件发送使用的邮箱
    $mail->addTo($_GET['email'], '获取用户注册激活码');        //定义邮件的接收邮箱
    $mail->setSubject('获取注册用户的激活码');                //定义邮件主题
    $mail->send($transport);                                //执行发送操作
    
/*   网络版发送邮件方法  */    
    $birthday='0000-00-00';
    if($_GET['birthday']!='')
        $birthday=$_GET['birthday'];
    $sql = "insert into tb_member(name,password,question,answer,email,realname,birthday,telephone,qq) values('".trim($_GET['name'])."','".md5(trim($_GET['pwd']))."','".$_GET['question']."','".$_GET['answer']."','".$_GET['email']."','".$_GET['realname']."','".$birthday."','".$_GET['telephone']."','".$_GET['qq']."')";

        if($num == 1){
            $reback = '1';
        }
    echo $reback;
?>

验证用户名是否被占用

chkname.php

<?php
include_once "conn/conn.php";
$sql = "select * from tb_member where name='".$_GET['name']."'";
$num = $conne->getRowsNum($sql);
if($num == 1){
    echo '2';
}else if($num == 0){
    echo '1';
}else{
    echo $conne->msg_error();
}
?>
