用phpmail发送邮件,简单实现php发邮件功能!

TANKING

很多网站都开始有邮箱验证码验证了。
例如网站评论有人回复了,你就能立马收到邮件。
这些功能是如何实现的呢?
其实就是用php实现的,当然这样的类很多,我这里给大家分享的是phpmail

首先该文件有一个封装类和一个配置

很简单,然后一个表单进行发邮件。

发件人是我的163邮箱
收件人是我的QQ邮箱

当我点击发送的时候,我就会在我的163邮箱的“已发送”列表看到一篇发送的邮件

然后登陆QQ邮箱就可以看到收件箱有一封刚刚发过来的邮件。
如果收件箱看不到,请到垃圾箱找找......我的是在垃圾箱找到的。

这就是整个发送过程!

上代码:

    if($state==""){
        echo "对不起,邮件发送失败!请检查邮箱填写是否有误。";
        echo "<a href='index.html'>点此返回</a>";
        exit();
    }
    echo "恭喜!邮件发送成功!!";
    echo "<a href='index.html'>点此返回</a>";
    echo "</div>";

?>

注意:$smtppass这里不是填邮箱的密码,填密码是不行的,要在163后台设置打开授权开关设置一个授权码,打开所有的服务即可。

一般发件人和收件人都在同一个网域就不会被拉入黑名单!发件人用腾讯的,收件人也用腾讯的,那就绝对没问题。
