How to use queue technology in ThinkPHP6

With the continuous development of Web websites and the increase in the number of users, the system's concurrent processing capabilities and task scheduling capabilities have become bottlenecks in the design. In order to solve these problems, queue technology is widely used in Web systems.

ThinkPHP6 is an excellent PHP development framework that provides powerful queue technology that can be used for asynchronous processing and scheduling of tasks. This article will introduce how to use queue technology in ThinkPHP6.

1. Overview of Queue Technology

Queue technology is a method of asynchronous processing of tasks. Tasks can be submitted to the queue, and then the background process or server processes these tasks asynchronously to alleviate the problem. The load pressure of the Web system.

Queue technology can be divided into two categories: message queue and task queue. Message queues are usually used to process messages that require immediate response, such as message notifications, etc. The task queue is used to asynchronously process tasks that require time and computing power.

In ThinkPHP6, the task queue is referred to as "queue", which consists of a message queue driver and a logging backend.

2. Queue technology usage steps

1. Installing the message queue driver

The message queue driver is a server program used to store and process task queues. In ThinkPHP6, multiple message queue drivers are supported, such as Redis, MySQL, etc.

Taking the Redis message queue as an example, you need to install the "topthink/think-queue" extension package and the "predis/predis" extension package in ThinkPHP6. The installation command is as follows:

composer require topthink/think-queue
composer require predis/predis

2. Configure queue parameters

In ThinkPHP6, Queue parameters need to be set in the configuration file, including driver type, driver parameters, queue name, etc. The configuration file path is "config/queue.php".

Configuration example:

return [

// 默认队列驱动：Redis
'default' => 'redis',

// 队列连接参数
'connections' => [
    'redis' => [
        'driver' => 'redis',
        'queue' => 'default', // 队列名称
        'connection' => 'default',
        'host' => '127.0.0.1',
        'port' => 6379,
        'password' => '',
        'database' => 0,
        'expire' => 60,
    ],
],

];

3. Writing task class

In ThinkPHP6 , the queue task class is located in the appjob directory. The task class must contain a method handle(), which is used to perform the specific logic of the task.

Task class example:

namespace appjob;

class SendEmail
{

public function handle($data)
{
    // 处理发送邮件任务的逻辑
    echo '发送邮件：' . $data['email'] . PHP_EOL;
}

}

4. Submit task To the queue

In the code, you can submit tasks to the queue by calling the push() or delay() method of the Queue class. The push() method directly submits the task to the queue, while the delay() method can set the delay time to process the task asynchronously.

Submit task example:

use think acadeQueue;
use appjobSendEmail;

//Submit asynchronous email sending task
$data = [

'email' => 'example@example.com',
'title' => '邮件标题',
'content' => '邮件内容',

];
$job = new SendEmail($data);
Queue::push($job);

// Submit delayed email sending task
$job = new SendEmail($data);
Queue::later(10, $job);

5. Start the queue background process

Finally, execute in the command line Start the queue background process command to start executing queue tasks:

php think queue:work

3. Summary

Queue technology is an excellent Web system Asynchronous processing and task scheduling methods can greatly improve the system's concurrent processing capabilities and task scheduling capabilities.

In ThinkPHP6, the use of queue technology is very simple. You only need to install the message queue driver, configure queue parameters, write task classes and submit tasks to the queue, and finally start the queue background process.

I hope this article can help you better understand and use the queue technology in ThinkPHP6.
