ThinkPHP6 is a popular PHP framework that provides many convenient features to help us develop efficient web applications. One of them is scheduled tasks. In this article, I will introduce how to use the scheduled task function of ThinkPHP6 to perform some tasks that need to be performed regularly, such as data backup, sending emails, etc.

  1. Installation

ThinkPHP6 uses Swoole's coroutine timer to achieve efficient scheduled task functions. Before you start using scheduled tasks, you need to make sure you have installed the Swoole extension.

In Composer, you can install Swoole through the following command:

composer require swoole/swoole

After installation, you need to enable the Swoole extension in the config/app.php file. Find the providers array and add thinkworkerProvider::class:

'providers' => [
    //…
    thinkworkerProvider::class,
],
  1. Define the task

In ThinkPHP6, you can use There are two ways to define scheduled tasks. One is by creating a command class named appcommand and the other is by extending the thinkworkerServer class. Here we adopt the latter.

In your project, you need to create a class that inherits from thinkworkerServer as shown below:

<?php
namespace appsocket;

use SwooleCoroutine;
use thinkworkerServer;

class Socket extends Server
{
    protected $socket;

    public function onWorkerStart()
    {
        // 此处可以定义在 Worker 进程启动时需要执行的操作
    }

    public function onConnect($server, $fd)
    {
        // 此处定义客户端连接时执行的操作
    }

    public function onReceive($server, $fd, $reactor_id, $data)
    {
        // 此处定义客户端发送数据时的操作
    }

    public function onClose($server, $fd)
    {
        // 此处定义客户端断开连接时的操作
    }

    public function onTask($server, $task_id, $src_worker_id, $data)
    {
        // 自定义任务处理方法
    }

    public function onFinish($server, $task_id, $data)
    {
        // 任务结束时的操作
    }

    public function onPipeMessage($server, $from_worker_id, $message)
    {
        // 此处定义进程间通讯的逻辑
    }
}

In the above example, we defined onWorkerStart()onConnect()onReceive()onClose()onTask()onFinish(), onPipeMessage() and other methods. These methods will be automatically executed when the corresponding event is triggered.

  1. Execute tasks

When we want to execute a method in a background task, we can use Swoole's# in onWorkerStart() ##tick() Method to set the execution frequency of scheduled tasks. For example, let's take the following code as an example:

public function onWorkerStart()
{
    // 每五秒执行一次 backup() 方法
    SwooleTimer::tick(5000, function () {
        (new Backup())->backup();
    });
}

In the above code, we set the

backup() method to be executed every 5 seconds. In this way, we can achieve tasks such as regularly backing up data and sending emails.

    Custom tasks
If you want to perform some more complex tasks and need to use some long-running operations during the task, you can use

onTask() and onFinish() methods to handle these tasks. For example,

public function onTask($server, $task_id, $src_worker_id, $data)
{
    // 此处可以定义需要在任务中执行的操作
    $result = (new Task())->execute($data);
    return $result;
}

public function onFinish($server, $task_id, $data)
{
    // 任务执行结束后的操作
    echo "Task #$task_id finished with result: $data
";
}

In the above code, we defined the

onTask() and onFinish() methods. The onTask() method defines the operations that need to be performed during the task, while the onFinish() method defines the operations after the task ends. If you need to perform some long-running operations in a task, you can use coroutines in the onTask() method.

    Summary
By using the scheduled task function of ThinkPHP6, you can achieve many operations that need to be performed regularly, such as data backup, sending emails and other tasks. You can define your own tasks according to your own needs and perform some long-running operations during task execution. I hope this article can help you better use the scheduled task function of ThinkPHP6.
