Utils

Hyperf provides a large number of convenient utils. Some commonly used and useful ones but not all of them are listed in this section. For more details, please refer hyperf/utils.

Coroutine Util

Hyperf\Utils\Coroutine

This util is used to assist in the judgment or operation of the coroutine.

id(): int

Get current coroutine ID by using static method id(). If it is not under the coroutine environment return -1.

create(callable $callable): int

The static method create(callable $callable) can be used to create a coroutine. It can also be done by using global method co(callable $callable) and go(callable $callable). The create(callable $callable) method is an encapsulation of the creation method in Swoole. The difference is that it will not throw out uncaught exceptions, which will be thrown by Hyperf\Contract\StdoutLoggerInterface as warning exceptions.

inCoroutine(): bool

inCoroutine() is a static method to determine whether it is currently in a coroutine environment.

Hyperf\Context\Context

The Context is used to handle coroutine context. It is basically an encapsulation of Swoole\Coroutine::getContext(). However, the Hyperf\Context\Context is compatible with running in a non-coroutine environment.

Hyperf\Utils\Coordinator\CoordinatorManager

The CoordinatorManager is used to schedule the coroutine when events occurred.

<?php
use Hyperf\Coordinator\CoordinatorManager;
use Hyperf\Coordinator\Constants;
use Hyperf\Utils\Coroutine;

Coroutine::create(function() {
    // Invoked after all OnWorkerStart event callbacks are completed
    CoordinatorManager::until(Constants::WORKER_START)->yield();
    echo 'worker started';
    // Assigning resources
    // Invoked after all OnWorkerStart event callbacks are completed
    CoordinatorManager::until(Constants::WORKER_EXIT)->yield();
    echo 'worker exited';
    // Recycling resources
});
