php我们可以使用系统的mail函数去发送邮件 但是需要配置一下邮件环境 这里选择使用PHPMailer 这样比较方便
首先下载PHPMailer:https://github.com/Synchro/PHPMailer
然后将下载好的文件夹解压放到根目录下即可
然后调用mail函数发送邮件:
比如:
<?php $to = "542633273@qq.com";
$subject = "Test mail";
$message = "Hello! This is a dsdsimple email message.";
$from = "542633273@qq.com";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
echo "Mail Sent."; ?>
--------------------------更新:上面的方法虽然简单方便,但是有个问题就是不稳地,有时候发送到垃圾邮箱里,有时候收不到邮件,所以不太实用.---------------------------
以下方法,主要是使用了一个障眼法,即发件人邮箱与收件人邮箱都是自己设定的,而真正的发件人邮箱是以内容的形式发送过去的,即用户在填写内容和自己邮箱信息后点击发送按钮,后台真正是通过我自己好邮箱A发送到我自己的邮箱B的 只不过用户真正有邮箱会通过内容的形式反映出来.这样做可以保证邮件的稳定性以及不会被当做垃圾邮件处理
/**
* 注：本邮件类都是经过我测试成功了的，如果大家发送邮件的时候遇到了失败的问题，请从以下几点排查：
* 1. 用户名和密码是否正确；
* 2. 检查邮箱设置是否启用了smtp服务；
* 3. 是否是php环境的问题导致；
* 4. $smtp->debug = false改为true，可以显示错误信息，然后可以复制报错信息到网上搜一下错误的原因；
* 5. 如果还是不能解决，可以访问：http://www.daixiaorui.com/read/16.html#viewpl
* 下面的评论中，可能有你要找的答案。
