Await for RxPHP
===============

[](#await-for-rxphp)

This library will allow observables to block until complete. For use when combining observables with imperative code.

It uses the [Voryx event-loop](https://github.com/voryx/event-loop) which behaves like the Javascript event-loop. ie. You don't need to start it.

### Basic Example

[](#basic-example)

```
require __DIR__ . '/../vendor/autoload.php';

//Do some aysnc craziness with observables
$observable = \Rx\Observable::interval(1000);

//Returns a `Generator` with the results of the observable
$generator = \Rx\await($observable);

//You can now use the results like a regular `Iterator`
foreach ($generator as $item) {

    //Will block here until the observable completes
    echo $item, PHP_EOL;
}
```

### Timeout Example

[](#timeout-example)

Since observables can return 1 to an infinite number of results, you'll need to make sure that you either limit the number of items you take or use a timeout or it could block forever.

```
require __DIR__ . '/../vendor/autoload.php';

$source = \Rx\Observable::interval(1000)
    ->takeUntil(\Rx\Observable::timer(10000)); //timeout after 10 seconds

$generator = \Rx\await($source);

foreach ($generator as $item) {
    echo $item, PHP_EOL;
}

echo "DONE";
```

```
$source = \Rx\Observable::interval(1000)
    ->take(5); //Limit items to 5

$generator = \Rx\await($source);

foreach ($generator as $item) {
    echo $item, PHP_EOL;
}

echo "DONE";
```
