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\Utils\Context
The Context
is used to handle coroutine context. It is basically an encapsulation of Swoole\Coroutine::getContext()
. However, the Hyperf\Utils\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\Utils\Coordinator\CoordinatorManager;
use Hyperf\Utils\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
});
