PHP 发送邮件
最近呢，再捣鼓一个类似商城的商城，买东西肯定的给用户发一下，告诉他，嘿，兄得，你的手已经剁完了，233，纯属玩笑，可是呢，该做的还是要做的，本来寻思用mail()函数，但是呢，简单事简单，但是呢，出错啊，发不出去，没时间解决这么多问题，来个简单的吧
用smtp类发送邮件
1、首先我就写了一个方法，因为配置在后台，直接取就好了，有的需要表单提交过来，只需要接收一下，把对应的值写一下就好了
2、类函数，只需要调用就好了，不需要修改
1、在控制器里面写个方法
header("Content-type:text/html;charset=utf-8");
require_once "Smtp.class.php";
$smtpserver = "ssl://smtp.qq.com";//SMTP服务器 其他的写stmp.xx.com就好了，QQ的不行，加了ssl://才可以
$smtpserverport =465;//SMTP服务器端口
$smtpusermail = "175787xxxx@qq.com";//SMTP服务器的用户邮箱
$smtpemailto = "123456yyyy@qq.com";//发送给谁
$smtpuser = "175787xxxx@qq.com";//SMTP服务器的用户帐号，注：部分邮箱只需@前面的用户名
$smtppass = "qq邮箱使用秘钥";//SMTP服务器的用户密码
$mailtitle = "邮件主题";//邮件主题
$mailcontent = "<h1>邮件内容</h1>";//邮件内容
$mailtype = "HTML";//邮件格式（HTML/TXT）,TXT为文本邮件
$smtp = new Smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//这里面的一个true是表示使用身份验证,否则不使用身份验证.
$smtp->debug = false;//是否显示发送的调试信息
$state = $smtp->sendmail($smtpemailto, $smtpusermail, $mailtitle, $mailcontent, $mailtype);
if($state==""){
echo "error";
echo "<a href='index.html'>点此返回</a>";
exit();
}else{
echo "ok";
}
2、类文件 Smtp.class.php ，直接引入就好了，不需要修改

文件有，如果需要可以联系我，直接给你源文件好了，我特么的竟然不知道在哪里可以放文件，又垃圾了。
