hello example no works

require './vendor/autoload.php'; function getAwesomeResultPromise() { $deferred = new React\Promise\Deferred(); // Execute a Node.js-style function using the callback pattern computeAwesomeResultAsynchronously(function ($error, $result) use ($deferred) { if ($error) { $deferred->reject($error); } else { $deferred->resolve($result); } });

// Return the promise
return $deferred->promise();

} getAwesomeResultPromise() ->then( function ($value) { // Deferred resolved, do something with $value }, function ($reason) { // Deferred rejected, do something with $reason } );

Error:

PHP Fatal error: Uncaught Error: Call to undefined function computeAwesomeResultAsynchronously() in /tmp/proc/promise/test.php:8 Stack trace:

0 /tmp/proc/promise/test.php(20): getAwesomeResultPromise()

1 {main}

thrown in /tmp/proc/promise/test.php on line 8

I take an example from the readme example and it does not work why?

You have to implement the computeAwesomeResultAsynchronously function to work this example.
