How to use PHP queue to improve the concurrent performance of email sending?

Email sending is one of the commonly used functions in many systems, but when sending emails on a large scale, performance bottlenecks are often encountered. In order to improve the concurrency performance of email sending, we can use PHP queues to achieve this.

Benefits of using queues
The benefit of using queues is that you can asynchronously send mail tasks, put the tasks in the queue, and let the background process execute the tasks one by one, thereby improving concurrency performance. In this way, even if there are abnormalities or network delays during the email sending process, the user's operations will not be affected.

Specific code examples

1. Installing queue extension
   First, we need to install a PHP queue extension, commonly used ones areBeanstalkd,RedisandRabbitMQetc. Here isBeanstalkdas an example.

   pecl install beanstalkd

   Copy after login

2. Create an email sending task class
   We can create an email sending task class to handle email sending logic.

   class MailJob { public function fire($job, $data) { // 邮件发送逻辑 $to = $data['to']; $subject = $data['subject']; $message = $data['message']; // 使用邮件发送库进行发送 // ...省略代码... // 发送完毕后删除任务 $job->delete(); } }

   Copy after login

3. Add the task to the queue
   Add the email sending task to the queue where you need to send the email.

   $jobData = [ 'to' => 'example@example.com', 'subject' => '邮件标题', 'message' => '邮件内容', ]; // 连接队列服务器 $queue = new PheanstalkPheanstalk('127.0.0.1'); // 将任务加入队列 $queue->useTube('mail')->put(json_encode($jobData));

   Copy after login

4. Create queue consumer
   Create a background process to listen to the queue and perform tasks.

   $queue = new PheanstalkPheanstalk('127.0.0.1'); // 监听队列 while (true) { $job = $queue->watch('mail')->reserve(); $data = json_decode($job->getData(), true); // 处理消息 $mailJob = new MailJob(); $mailJob->fire($job, $data); }

   Copy after login

5. Start the queue consumer
   Execute the queue consumer script to start the queue consumer and keep the process running.

   php queue_consumer.php >> /dev/null 2>&1 &

   Copy after login
6. Scaling and Monitoring
   In order to improve concurrency performance, tasks can be processed in parallel by adding multiple queue consumers. In order to conveniently monitor the running status of the queue, you can use some queue management tools, such asSupervisorandMonit.

Summary
By using PHP queues to handle email sending tasks, the concurrency performance of email sending can be improved. Using the asynchronous processing characteristics of the queue can not only improve the user's response speed, but also ensure the stability of the system. I hope this article can help you understand how to use PHP queues to improve the concurrency performance of email sending.
