[PHP知识库]基于workerman tp6实现定时任务

• 安装依赖

composer?require?workerman/workerman

• 创建定时器timer

php?think?make:command?Timer

• 定时器代码

class Timer extends Command
{
    /**
     * @var int
     */
    protected $timer;
    /**
     * @var int|float
     */
    protected $interval = 2;
    protected function configure()
    {
        // 指令配置
        $this->setName('timer')
            ->addArgument('status', Argument::REQUIRED, 'start/stop/reload/status/connections')
            ->addOption('d', null, Option::VALUE_NONE, 'daemon（守护进程）方式启动')
            ->addOption('i', null, Option::VALUE_OPTIONAL, '多长时间执行一次')
            ->setDescription('开启/关闭/重启 定时任务');
    }
    protected function init(Input $input, Output $output)
    {
        global $argv;
        if ($input->hasOption('i'))
            $this->interval = floatval($input->getOption('i'));
        $argv[1] = $input->getArgument('status') ?: 'start';
        if ($input->hasOption('d')) {
            $argv[2] = '-d';
        } else {
            unset($argv[2]);
        }
    }
    protected function execute(Input $input, Output $output)
    {
        $this->init($input, $output);
        //创建定时器任务
        $task = new Worker();
        $task->count = 1;
        $task->onWorkerStart = [$this, 'start'];
        $task->runAll();
    }
    public function stop()
    {
        //手动暂停定时器
        \Workerman\Lib\Timer::del($this->timer);
    }
    public function start()
    {
        $last = time();
        $task = [6 => $last, 10 => $last, 30 => $last, 60 => $last, 180 => $last, 300 => $last];
        
        $this->timer = \Workerman\Lib\Timer::add($this->interval, function () use (&$task) {
            //每隔2秒执行一次
            try {
                $now = time();
                foreach ($task as $sec => $time) {
                    if ($now - $time >= $sec) {
                        //每隔$sec秒执行一次
                        $task[$sec] = $now;
                    }
                }
            } catch (\Throwable $e) {
            }
        });
    }
}

• 注册 Timer 命令

'commands' => [
        //定时任务命令
        'timer'=>\app\command\Timer::class,
    ],

Timer 参数说明

Usage:

??timer?[options]?[--]?<status>

Arguments:

??status????????????????start/stop/reload/status/connections

Options:

??????--d???????????????daemon（守护进程）方式启动

??????--i[=I]???????????多长时间执行一次,可以精确到0.001

定时器操作

• php?think?timer?start? //开启
• php?think?timer?stop? //停止
