1.5秒后执行某些PHP数据时出现问题

Question

I have some PHP code whereby I post data to an API and get some response data. When a user pays the response status from the API should change. I am trying to delay the execution of PHP code and wait for 15 seconds before getting the payment status from the API which is not working as expected.. I have no idea how to do that in PHP or rather Laravel Queues since am using Laravel 5.4

~ Kindly assist?

 $data = array(
            'payment_reference' => $checkID,
            'payment_type' => $type
        );

        //Post request to an API and get the status and store in a variable
        $paySt = $this->global_Curl($data, 'api/payment/status')->data;

        sleep(15);

        //Second call to the API after sleep to check if status has changed
       $payStat = $this->global_Curl($data, 'api/payment/status')->data;

        if($payStat->status === '1'){
             return 'true';   
        }

sleep() function is used to delay the current execution

In your case, you need to again call the payment api after 4-5 sec delay

For Example:

#Payment process hit code

#sleep(4); //delay/wait for 4 second

#Again run code to check the payment status.
