PHP キューを使用してメール関連の例外を処理するにはどうすればよいですか?

sudo apt-get install beanstalkd

sudo systemctl start beanstalkd

pecl install beanstalkd

extension=beanstalkd.so

sudo systemctl restart php-fpm

class MailQueue

    protected $beanstalk;

    public function __construct()
    {
        $this->beanstalk = new PheanstalkPheanstalk('127.0.0.1');
    }

    public function sendEmail($email, $subject, $message)
    {
        // 将邮件任务加入队列
        $this->beanstalk->useTube('mail_queue')->put(json_encode([
            'email' => $email,
            'subject' => $subject,
            'message' => $message,
        ]));
    }

    public function handleEmails()
    {
        // 监听队列并处理邮件发送逻辑
        while (true) {
            $job = $this->beanstalk->reserveFromTube('mail_queue');
            $data = json_decode($job->getData(), true);
            
            // 发送邮件逻辑，这里省略具体实现
            $this->sendEmail($data['email'], $data['subject'], $data['message']);
            
            // 删除任务
            $this->beanstalk->delete($job);
        }
    }
}

$mailQueue = new MailQueue();
$mailQueue->sendEmail('example@example.com', '邮件主题', '邮件内容');
