ReactPHP awaitable observable
Installation
To install via Composer, use the command below, it will automatically detect the latest version and bind it with ^.
composer require wyrihaximus/react-awaitable-observable
Usage
The awaitObservable function will accept any observable and turn it into an iterator, so it can be used inside async in an foreach:
use Rx\Observable;
use Rx\Scheduler\ImmediateScheduler;
use function React\Async\async;
use function WyriHaximus\React\awaitObservable;
async(function () {
$observable = Observable::fromArray(range(0, 1337), new ImmediateScheduler());
foreach (awaitObservable($observable) as $integer) {
echo $integer; // outputs 01234....13361337
}
});
Breaking the iterator
The example above assumes you won't break the iterator. There are however situations where you want to short circuit the iterator, for such situations the break method is provided.
use Rx\Observable;
use Rx\Scheduler\ImmediateScheduler;
use function React\Async\async;
use function WyriHaximus\React\awaitObservable;
async(function () {
$observable = Observable::fromArray(range(0, 1337), new ImmediateScheduler());
$iterator = awaitObservable($observable);
foreach ($iterator as $integer) {
echo $integer; // outputs 01234
if ($integer >= 4) {
$iterator->break();
}
}
});
