Parameter Description

Closure parameters

Parameters	Type	Description
$cancel	Closure	Callback function to cancel the current recurring task

Overview

Repeat (repeated execution), specify the frequency to do something repeatedly, usually used in scenarios such as scheduled tasks. ripple will provide a cancel callback function for the closure function you submitted. The current repeated task can be canceled by calling the cancel function.

Basic usage

\Co\repeat(function (Closure $cancel) {
    echo 'delay task';
    
    
    if(rand(1, 10) === 10){
        $cancel();
    }
}, 1);

\Co\wait(); // Wait for all events to complete

Note: The repeat method will repeatedly execute the closure function within the specified time interval until the cancel function is called.

\Co\repeat(function (Closure $cancel) {
    \Co\sleep(10);
    
    echo 'delay task';
    
    $cancel();
}, 1);

\Co\wait();

In the above example, the code in repeat will be executed after 1 second, and when encountering \Co\sleep, the current coroutine will be automatically suspended, but repeat will still be executed again after 1 second.
