Reading some comments here and it does confuse me Promises, async and await in javascript, coroutines and threads in kotlin, fibers in some language runtime (including this php 8.1 [0]), single process (nodejs), multi-process(php-fpm worker), single-thread, multi-thread, goroutines in go, multi-core coroutines Googling the definitions and x vs y situation helps a little, the main confusion to me is why some people want this xyz feature in a language runtime and not the other, the pros and cons are seriously so confusing I have probably used several, like promises, async, await, like others said async would be implement on fibers [1] (is php 8.1 implementation same as V8,spidermonkey,javascriptcore? or any other language runtime). And I have tried to understand kotlin coroutines as well modern times to run php, people would use php-fpm with nginx, it is running multiple worker (single) process, so why would anyone [2], [3] wants multi-core coroutines in it? What does it even mean? Writing this out ease my mind a bit yea, need to be able to communicate the confusion instead of just saying "programming is difficult" [0]: https://news.ycombinator.com/item?id=29343773 https://news.ycombinator.com/item?id=29343773 [1]: https://news.ycombinator.com/item?id=29344427 https://news.ycombinator.com/item?id=29344427 [2]: https://news.ycombinator.com/item?id=29344704 https://news.ycombinator.com/item?id=29344704 [3]: https://news.ycombinator.com/item?id=29345986 https://news.ycombinator.com/item?id=29345986

Not everyone does. There's also https://reactphp.org https://reactphp.org (which is an event loop runtime, similar to Node), and https://amphp.org https://amphp.org (also event loops), and Swoole https://github.com/swoole/swoole-src https://github.com/swoole/swoole-src (coroutine runtime, similar to Go). Fibers are basically an API that event-loop runtime libs can use so that userland code doesn't need to use promises or generators to run non-blocking operations. Fibers are not useful for php-fpm or swoole users.

Not all PHP is behind a web server. Think long running workers, queue consumers, daemons etc.
