How to send multiple requests at once ReactPHP?

Question

I am using guzzle to send some requests:

$response = $this->client->request(new SomeObject());

using the class below

...
public function request(Request $request)
{
    return $this->requestAsync($request)->wait();
}

// Here I'm using Guzzle Async, but I can remove that is needed
public function requestAsync(Request $request)
{
    $promise = $this->http->requestAsync($request->getMethod(), $request->getUri());

    $promise = $promise->then(
        function (ResponseInterface $response) use ($request) {
            return $response;
        }
    );

    return $promise;
}
...

I would like to use ReactPHP to send multiple requests at once in a foreach loop:

$requests = [];
foreach ($data as $value) {
    $requests[] = $this->client->request(new SomeObject());
}

// pass $requests to ReactPHP here and wait on the response

Any ideas?

First of all, you don't need ReactPHP to use parallel HTTP requests with Guzzle. Guzzle itself provides this feature (if you use cURL handler, which is the default).

For example:

$promises = [];
foreach ($data as $value) {
    $promises[] = $guzzleClient->getAsync(/* some URL */);
}

// Combine all promises
$combinedPromise = \GuzzleHttp\Promise\all($promises)

// And wait for them to finish (all requests are executed in parallel)
$responses = $combinedPromise->wait();

If you still want to use Guzzle with ReactPHP event loop, then, unfortunately, there are no straightforward solution. You cat take a look at https://github.com/productsupcom/guzzle-react-bridge (I'm the developer, so feel free to ask questions).
