Works like Javascript's setTimeout/setInterval.
Async::async() also runs the next piece of code independently (much like requestAnimationFrame or setImmediate/nextTick).
composer require jolharg/async
<?php
namespace Whatever;
use Jolharg/Async;
class Whatever
{
public function whatever()
{
Async::async(function() { echo 'hi'; })
}
public function somethingElse()
{
Async::setTimeout(function() { echo 'hi'}, 1000);
Async::setInterval(function() { echo 'hi'}, 2000);
}
}
