1、使用 composer 下载 phpmailercomposer require phpmailer/phpmailer
2、自定义 Mailer.php 文件，我使用的是TP5.1的框架测试，可自定义了参数弄的有点乱，大家将就下<?php
namespace util;
use PHPMailer\PHPMailer\PHPMailer;
class Mailer
{
// 编码格式为utf8，不设置编码的话，中文会出现乱码
protected $charSet = 'utf-8';
// 发送方的SMTP服务器地址，QQ邮箱为：smtp.qq.com
protected $host = 'smtp.163.com';
// 163邮箱的ssl协议方式端口号是465/994 QQ邮箱的ssl协议方式端口号是465/587
protected $port = 465;
// 是否使用身份验证，默认false
protected $smtpAuth = true;
// 发送方的邮箱用户名，就是你申请163的SMTP服务使用的163邮箱，或者QQ邮箱等
protected $mailUsername = '';
// 发送方的邮箱密码，注意用163邮箱这里填写的是“客户端授权密码”而不是邮箱的登录密码！QQ邮箱同理，如果没有授权码就是邮箱密码
protected $mailPassword = '';
// 使用ssl协议方式
protected $smtpSecure = 'ssl';
// 错误调试，默认关闭
protected $smtpDebug = 0;
// 发送邮件地址
protected $mailFrom = '';
// 发送名称
protected $mailFromname = '';
// 回复邮箱地址
protected $replyMail = '';

3、测试# 需要引入文件
use util\Mailer;
# 使用
$Mailer = new Mailer();
# 发送
$email = '****@qq.com';
$options = [
'cc' => [
['email'=>'****@163.com', 'name'=>'163邮箱1']
],
'bcc' => [
['email'=>'****@qq.com', 'name'=>'QQ邮箱2']
],
];
$res = $Mailer->sendEmail($email, '测试标题', '测试内容', 'QQ邮箱1', $options);
print_r($res);
注意：发送附件不能使用URL文件地址
