首先这是一个封装的phpmailer控制器方法，可以直接用

也是其次，这是一个实现了基本发送邮件的代码，

功能包括，发送方，收件方，抄送方，包括邮件附件，暂不支持回复功能，其实只要按照格式加上回复那一部分代码就可以了~

直接上代码：

MailController.php

<?php

namespace mason;

use PHPMailer\PHPMailer\Exception;

    /**
     * * phpmailer邮件对象

调用方式：

$config = [
    //'debug_output' => true, //调试专用
    'SMTPAuth' => true,
];
$data = [
    'username' => $param['sendEmail'], //用户邮件地址
    'password' => $param['emailPassword'], //用户配置的密码
    //'password' => 546345643, //测试异常接收功能，实际运行可删除此行代码
    'sendTo'=>$sendTo, //发送方
    'copyTo'=>$copyTo, //抄送方
    'file'=>array_merge($uploadArr, [public_path('static').$file_path]), //附件，都是地址，最好是本地地址
    'setFrom' => $param['sendEmail'], //谁发送的，用来显示在邮件列表的名称
    'Subject' => '邮件标题', //邮件标题
    'Body' => $user['nick_name'] . "的".date('Y-m-d')."日报已提交, 本邮件由系统自动发送" //邮件内容，这里只是一段话，具体的格式支持请查看文档自行修改
];
$mail = new MailController($config, $data);
$mail->send();

以上~
