如下图所示，为啥不能做个这样调用无效。，感觉更方便维护

Crontab的构造函数第二个参数接受的是一个callback,所以你的姿势不对,应该这样

<?php
namespace process;

use Workerman\Crontab\Crontab;

class Task
{
    public function onWorkerStart()
    {
        new Crontab('* * * * * *', $this->abc());
    }

    public function abc() {
        return function() {
            echo "callback\n";
        };
    }

}

正确姿势应该是

<?php
namespace process;

use Workerman\Crontab\Crontab;

class Task
{
    public function onWorkerStart()
    {
        new Crontab('* * * * * *', [$this, 'abc']);
    }

    public function abc() {
        return function() {
            echo "callback\n";
        };
    }

}
