1、使用composer下载phpmailercomposerrequirephpmailer/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
namespaceutil;
usePHPMailer\PHPMailer\PHPMailer;
classMailer
{
//编码格式为utf8，不设置编码的话，中文会出现乱码
protected$charSet='utf-8';
//发送方的SMTP服务器地址，QQ邮箱为：
protected$host='';
//163邮箱的ssl协议方式端口号是465/994QQ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='';

//发送邮件
if(!$mailer->send()){
//输出错误信息
return['code'=>1,'msg'=>$mailer->ErrorInfo];
}
return['code'=>0];

3、测试#需要引入文件
useutil\Mailer;
#使用
$Mailer=newMailer();
#发送
$email='****@';
$options=[
'cc'=>[
['email'=>'****@','name'=>'163邮箱1']
],
'bcc'=>[
['email'=>'****@','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
