Use PHPMailer to send emails in ThinkPHP6

ThinkPHP6 is a PHP development framework based on MVC architecture. It provides many convenient functions in daily development, including the function of sending emails. This article will introduce how to use PHPMailer to send emails in ThinkPHP6.

1. Install PHPMailer

PHPMailer is an open source PHP email sending class. We can install it through Composer. Run the following command in the project root directory:

composer require phpmailer/phpmailer

After the installation is complete, we can use PHPMailer in the code.

2. Configure email sending parameters

Before starting to send emails, we need to configure the relevant parameters for email sending, including SMTP server, port, account password, etc. We can create a new mail.php file in the application's config directory to save the parameter configuration for email sending. The code is as follows:

<?php

return [
    'host'       => 'smtp.qq.com',
    'port'       => 465,
    'username'   => '邮箱账号',
    'password'   => '邮箱密码',
    'mail_from'  => '发件人邮箱地址',
    'name_from'  => '发件人名称',
    'mail_reply' => '回复邮件地址',
];

3. Write the email sending function

Now we are ready After configuring the parameters required for email sending, we can start writing the email sending function. In ThinkPHP6, we can send emails by customizing a mail service. First, we need to create a new service directory under the application directory and create a new MailService class in it. The code is as follows:

<?php

namespace appservice;

use PHPMailerPHPMailerPHPMailer;
use thinkacadeConfig;

class MailService
{
    public function sendMail($to, $subject, $content)
    {
        $mail = new PHPMailer();
        $config = Config::get('mail');

        $mail->isSMTP(); // 使用SMTP服务发送邮件
        $mail->SMTPAuth = true; // 启用 SMTP 认证
        $mail->Host = $config['host']; // SMTP 服务器
        $mail->Port = $config['port']; // SMTP服务器的端口号
        $mail->Username = $config['username']; // SMTP账号
        $mail->Password = $config['password']; // SMTP密码

        $mail->From = $config['mail_from']; // 发件人邮箱
        $mail->FromName = $config['name_from']; // 发件人名称
        $mail->isHTML(true); // 邮件正文是否为html编码
        $mail->CharSet = 'utf-8'; // 设置邮件字符集
        $mail->addAddress($to); // 收件人邮箱地址
        $mail->Subject = $subject; // 邮件标题
        $mail->Body = $content; // 邮件内容

        if (!$mail->send()) {
            return $mail->ErrorInfo;
        } else {
            return true;
        }
    }
}

In the above code , we used the SMTP method provided by PHPMailer to send emails. Since configuration information needs to be read when sending emails, we use the Config class to obtain the parameter configuration for email sending in the code.

4. Use the email sending function

After completing the writing of the email sending function, we need to call this function in the controller. The following is a simple sample code:

<?php

namespace appcontroller;

use appserviceMailService;

class Index
{
    public function index()
    {
        $to = '收件人邮箱地址';
        $subject = '邮件标题';
        $content = '邮件内容';

        $mailService = new MailService();
        $result = $mailService->sendMail($to, $subject, $content);
        if($result === true){
            echo '发送成功';
        }else{
            echo '发送失败，错误信息：' . $result;
        }
    }
}

By calling the sendMail method in MailService, we can easily send emails.
