如何从PHP中获取Guzzle async http客户端的最快响应

I want to use Guzzle to send HTTP requests to multiple endpoints and I want to use the response that comes in first, rather than waiting for all requests to complete.

My code:

    $client = new \GuzzleHttp\Client();

    $p1 = $client->requestAsync('GET', 'slow.host');
    $p2 = $client->requestAsync('GET', 'fast.host');

    $any = \GuzzleHttp\Promise\any([$p1, $p2]);
    $response = $any->wait();

I was expecting that as soon as either of the promises ($p1, $p2) gets resolved, I would get a response, however that's not how it works with Guzzle. Guzzle will always wait for $p1 to either resolve or reject, even if it takes forever.

From the example above, if the slow.host takes 10 seconds to send a response, and the fast.host takes 1 second to send a response, I would have to wait 10 seconds anyway. I would get the response from fast.host only in case slow.host fails completely (promise gets rejected, no such host, etc).

How do I get the fastest response immediately and ignore the rest?
