How to check my parent and child process executed in parrallel??

[developeronboard]

use Spatie\Async\Pool;
public function save(){
//my parent function goes
//my child process starts
$pool[] = async(function () use($data) {
sleep(3);
})->then(function ($output) {
})->catch(function ($exception) {
});
await($pool);
sleep(3);
}
To check I included sleep(3) in both parent and child process and it takes 6 seconds but i think this was not correct because if it was executed in parallel means it has to take only 3 seconds. Please guide me for this issue.

Please take a look at #97, carefully read the README: https://github.com/spatie/async/blob/master/README.md , and come back if it's still not clear after reading that.

am confused..can you explain How to check my parent and child process executed in parrallel??

[brendt]

Have you read up on how this package works?

[developeronboard]

Yeah but able to find some little codes :( can u give a link or explain the parent child process??
[https://dev.to/webong/using-asynchronous-processes-in-php-7io] i refered this link..is this correct?

[brendt]

Maybe this can be of help: https://stitcher.io/blog/asynchronous-php

I'm sorry but I don't have the time to explain the core ideas of async programming in PHP, but I'm sure you can find some good literature online.

Thank you Brendt, if you have time please try to provide codes with some examples in documentation surely it will make this package more good.

It will be hard for him to produce the examples. What seems to be missing is the fact, this package as laid out is not standalone.

When this package calls ->wait() what else in your code base is allowed to run?
The whole constructs here need some other event loop like process to check the actual process status, then let other things run. His link in explaining/comparing to other completing packages, does just that.

As commented #98 the async\await as used is misplaced here.
It might be best for this package to finish up on #4 (comment).

Anyway, I extracted and reworked various parts of this package into a bigger package. The heart symplely/processor is the wrapper API for symfony/process, forked and renamed from PR.
