### How this work?

Well its basically "exec" with serialised closure. "Dressed" in nice libs like symfony process and console.

I serialise callable function and sent to child process by exec. To get callback I register shutdown function and wait for process to finish.

### Why not pcntl ?

- Pcntl extension fork, so you can forget using it in web applications like apache2/php-fpm etc its only for CLI

- forks retains the parent state (for example open files) so its problematic

### Problems ?

- Calling exec is slower then fork

- Some resource/function/data must be passed directly to closure

### Some research

- https://www.phproundtable.com/episode/asynchronous-php - good start to "know how" make php async

- https://amphp.org/ - non-blocking framework for PHP

### Example ?

Sure take a look - https://github.com/krowinski/async/blob/master/example/example.php

### User cases (mostly some code on website that user don't need to wait for)

- send callback

- publish to queue amqp

- send external analytic data

- remove files 

- process payments

### Supports M$ Windows?

NO.

### TODO 

- tests
