FAQ

Why does the manager throw on unsupported runtimes instead of running synchronously?

Because the library is intentionally a real process orchestration package. Silent fallback to synchronous execution would change semantics and make lifecycle coordination misleading. See Installation.

Can I wait for every worker without storing each group?

Yes. Calling $manager->wait() with no arguments waits for every worker created by that manager. See Worker Groups.

Can I signal only one worker?

Yes. Worker::kill() targets a single worker, and ForkManager::kill() can mix individual workers and worker groups in the same call. See Signals.

Can I read output before workers finish?

Yes. getOutput() and getErrorOutput() may return partial output while workers are still running. See Output and Errors.

Why is direct fwrite(STDOUT, ...) not captured?

Because the library currently captures buffered userland output through its own transport instead of redirecting native file descriptors. See Output and Errors.

Can I reuse the same manager inside a worker to create nested workers?

No. The same manager instance cannot be reused from inside one of its workers. Create a new manager inside that worker if you need a nested process tree. See Getting Services.

Does the library provide container aliases or singletons?

No. The package intentionally does not include aliases, singleton helpers, or service-provider abstractions. See Extending and Customizing.

Can I integrate the manager with a PSR-11 container?

Yes. The package is not coupled to PSR-11, but it can be registered through a factory in any application container. See Getting Services and Integration.

Can I inject my own logger?

Yes. Pass any Psr\Log\LoggerInterface implementation to the manager constructor. See Integration.

What exception should I catch if I only care about library-owned failures?

Catch FastForward\Fork\Exception\ForkExceptionInterface . See Exceptions.

Does this package work for standard HTTP request handling?

Not as a primary target. It is designed for CLI-oriented runtimes with POSIX process control. See Compatibility.

Where should I start if I want a hands-on walkthrough?

Start with the numbered examples in examples/ and the quickstart page in Quickstart.
