    The Fiber class

    (PHP 8 >= 8.1.0)

    Introduction

    Fibers represent full-stack, interruptible functions. Fibers may be suspended from anywhere in the call-stack, pausing execution within the fiber until the fiber is resumed at a later time.

    Class synopsis

    final class Fiber {
    /* Methods */
    public function __construct(callable $callback)
    public function start(mixed ...$args): mixed
    public function resume(mixed $value = null): mixed
    public function throw(Throwable $exception): mixed
    public function getReturn(): mixed
    public function isStarted(): bool
    public function isSuspended(): bool
    public function isRunning(): bool
    public function isTerminated(): bool
    public static function suspend(mixed $value = null): mixed
    public static function getCurrent(): ?Fiber
    }
