[PHP知识库]PHP邮件发送服务

1. phpmailer/phpmailer

Composer 仓库搜索 email 找到的扩展

这么优雅的代码

2. 名词解释

setFrom

设置邮件 发件人

addAddress

添加邮件 接件人

addCC 和 addBCC

CC代表抄送，英文全称是 Carbon Copy
BCC代表暗抄送，英文全称是 Blind Carbon Copy。

暗抄送和抄送的唯一区别就是，

暗抄送能够让各个收件人只查看到邮件，而不能看到其他收件人的地址。

addReplyTo

回件(回复邮件)的接收人, 如果未设置 replay, 那么回件的接件人为发件人

应用场景： 公司发送邮件， 通知所有人发送个人资料给人事 (邮件由公司统一发送的， 而邮件回件接收人确实人事)

addAttachment

添加附件

Subject

设置邮件主题

3. Example

//创建项目目录
mkdir example-phpmailer
cd example-phpmailer
// 安装 phpmailer
composer require phpmailer/phpmailer

// 创建 测试文件
touch index.php

index.php 内容如下, 以 QQ 邮箱为例， 密码需要修改为个人配置

<?php 

//Import PHPMailer classes into the global namespace
//These must be at the top of your script, not inside a function
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

//Load Composer's autoloader
require 'vendor/autoload.php';

//Create an instance; passing `true` enables exceptions
$mail = new PHPMailer(true);

try {
    //Server settings
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;  // Enable verbose debug output
    $mail->isSMTP();  // Send using SMTP
    $mail->Host       = 'smtp.qq.com';  // Set the SMTP server to send through
    $mail->SMTPAuth   = true;  // Enable SMTP authentication
    $mail->Username   = 'Your Email Adress';  // SMTP username
    $mail->Password   = 'Your Email Password';  // SMTP password
    $mail->SMTPSecure = PHPMailer::ENCRYPTION_SMTPS;  // Enable implicit TLS encryption
    $mail->Port       = 465;  // TCP port to connect to; use 587 if you have set `SMTPSecure = PHPMailer::ENCRYPTION_STARTTLS`

    //Recipients
    $mail->setFrom('527147280@qq.com', '527147280');
    // $mail->addAddress('178912797@qq.com', '178912797');     //Add a recipient
    $mail->addAddress('1967599562@qq.com');               //Name is optional
    // $mail->addReplyTo('178912797@qq.com', 'Information');
    // $mail->addCC('cc@example.com');
    $mail->addBCC('178912797@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 = 'Here is the subject';
    $mail->Body    = 'This is the HTML message body <b>in bold!</b>';
    $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}";
}
