本篇记录的是我的发邮件的代码整理。用PHPMailer实现发邮件功能

下载phpmailer地址 https://github.com/PHPMailer/PHPMailer

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require './PHPMailer/src/Exception.php';
require './PHPMailer/src/PHPMailer.php';
require './PHPMailer/src/SMTP.php';


$mail = new PHPMailer(true);                              // Passing `true` enables exceptions
try {
    //Server settings
    $mail->SMTPDebug = 2;                                 // Enable verbose debug output
    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.qq.com';  							// Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'xxx@qq.com';                 // SMTP username
    $mail->Password = 'xxxx';                           // SMTP password  QQ邮箱授权码
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to

    //Recipients
    $mail->setFrom('xxx@qq.com', 'Mailer');
    $mail->addAddress('xxx@qq.com', 'Joe User');     // Add a recipient
    $mail->addAddress('xxx@qq.com');               // Name is optional
    $mail->addReplyTo('xxx@qq.com', 'Information');
    $mail->addCC('xxx@qq.com');
    $mail->addBCC('xxx@qq.com');

    //Attachments
    //$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
    //$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name

    //Content
    $mail->isHTML(true);                                  // Set email format to HTML
    $mail->Subject = 'Email title';
    $mail->Body    = 'Email body';
    $mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

    $mail->send();
    echo 'Message has been sent';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
