How can I convert guzzle/promises to reactphp/promise ?
As there is no done() method for guzzle/promises , I want to convert it to reactphp/promise

// $guzzlePromise is an instance of GuzzleHttp\Promise\Promise and is a result of third party library
$reactPromise = convert($guzzlePromise);

Using react/promise ^2.4 while doing $reactPromise = \React\Promise\resolve($guzzlePromise); will make react/promise convert it for you.

@WyriHaximus thanks for your reply
But there is a problem in this solution , now there is no difference between done() and then just done() returns void

I want to have uncaught exceptions

$guzzlePromise = new \GuzzleHttp\Promise\Promise();
$guzzlePromise
    ->then(function ($value) {
        throw new \Exception($value)
    });

$guzzlePromise->resolve('test');//Third party library

$reactPromise = \React\Promise\resolve($guzzlePromise)
    ->done();

As I use done() I expect Fatal error: Uncaught exception 'Exception' but there is no fatal error just a rejected promise

I want to tell more details about my problem
I use a third party library based on \GuzzleHttp\Promise\Promise , My application handle errors with exceptions and I have a Uncaught exception handler to manage them , So sometimes I need to consume promise , something like done() to force promise throws exceptions instead of reject promise

1- How can I do this with React\Promise
2- Can I do this in \GuzzleHttp\Promise\Promise

You need to cast to a React\Promise before calling thenon it.

$guzzlePromise = new \GuzzleHttp\Promise\Promise();

$reactPromise = \React\Promise\resolve($guzzlePromise)
    ->then(function ($value) {
        throw new \Exception($value)
    })
    ->done();

$guzzlePromise->resolve('test');//Third party library

@jsor thanks for your reply
I run your code but there is no Fatal error: Uncaught exception 'Exception'
Where is my problem?! I check that throw new \Exception($value) is executed

This exception caught by guzzlehttp/promises/src/Promise.php:214

[jsor]

Sorry, i replied too fast :/
Since GuzzleHttp\Promise\Promise provides no done, it's not possible to let rejections bubble out.

@jsor thank you
Can you please see this issue aws/aws-sdk-php#1105

[jsor]

I've proposed #68 which uses done() instead of then()if available when resolving foreign thenables. This solves this issue when merged and guzzlehttp/promises implements done().

[sm2017]

So guzzlehttp/promises must be implement done() otherwise it dont works?
I understand right?

[WyriHaximus]

Correct
