php在原生代码中如何简单快速的发送email

骑猪看日落 2022-08-21 10:44 192阅读 0赞

<?php
 header("content-type:text/html;charset=utf-8");
 include("class.phpmailer.php");
 include("class.smtp.php");
 $mail = new PHPMailer();
 $mail->IsSMTP(); // send via SMTP
 $mail->Host = "smtp.163.com"; // SMTP servers
 $mail->SMTPAuth = true; // turn on SMTP authentication
 $mail->Username = "邮箱用户名"; // SMTP username 注意：普通邮件认证不需要加 @域名
 $mail->Password = "邮箱密码"; // SMTP password
 $mail->From = "发件人邮箱@163.com"; // 发件人邮箱
 $mail->FromName = "发件人"; // 发件人
 $mail->CharSet = "utf-8"; // 这里指定字符集！
 $mail->Encoding = "base64";
 $mail->AddAddress("收件人邮箱@163.com","toyou"); // 收件人邮箱和姓名
 $mail->AddReplyTo("收件人地址@163.com","wo");
 //$mail->WordWrap = 50; // set word wrap 换行字数
 //$mail->AddAttachment("/var/tmp/file.tar.gz"); // attachment 附件
 //$mail->AddAttachment("/tmp/image.jpg", "new.jpg");
 $mail->IsHTML(true); // send as HTML
 // 邮件主题
 $subject="邮件标题";
 $mail->Subject = $subject;
 // 邮件内容
 $mail->Body = "
 邮件发送的内容
 ";
 $mail->AltBody ="text/html";
 if(!$mail->Send())
 {
 echo "邮件发送有误 ";
 echo "邮件错误信息: " . $mail->ErrorInfo;
 exit;
 }
 else {
 echo "邮件发送成功! ";
 }

在这里你如果想使用原生代码进行发送email，那么在这里的前提是必须要引用class.smtp.php和class.phpmailer.php这两个类。否则则无法使用

class.phpmailer.php访问这个网站，复制代码，重新建立一个class.phpmailer.php

http://blog.csdn.net/haoyunyun888/article/details/51245003

class.smtp.php复制这个类中代码重新建立一个class.smtp.com
