CakePHP 3.0“找不到线程类”

Question

I want to implement the threading concept in CakePHP 3.0 , But when I try to extend the thread class, it gives an error of "Thread class not found"

I have also implemented it in core php and its working as expected, But somehow its not working with cakephp.

Here is the corephp code

<?php

class AsyncOperation extends Thread {

    public function __construct($arg) {
        $this->arg = $arg;
    }

    public function run() {
        if ($this->arg) {
            $sleep =  rand(1,60);
            for ($i=0; $i < 100 ; $i++) { 
                sleep(1);
                echo $this->arg."----------->".$i."<br/>";    
            }
        }
    }
}

class CallingClass {
    public function runScript($var)
    {
        print_r("start run script");
        $th = new AsyncOperation($var);
        $th->start();
        print_r("continue running");

    }
}

$wow =  new AsyncOperation("First");
$wow->start();
$wow2 =  new AsyncOperation("Last");
$wow2->start();
?>   

And in CakePHP 3

class AsyncOperation extends Thread
