Feature proposal - $client->send() - return a Promise

[FGIKCM]

For now, there is no way with the client to send data, THEN close the stream when everything is sent. The $client->send('message) is not in a Promise, so doing the following will not (always) work, as the stream may be closed before everything is sent:

$client->send('chain1');
$client->send('chain2');
$client->close();

Should it be possible to have a similar function, which would returns a Promise? This way, we would have a clean way to send messages, THEN closing the stream.
For example:

$client->sendInPromise('chain1chain 2')->then(function() use ($client) {$client->close()});

Hey @FGIKCM, excellent question!

It looks like this boils down to a lack of good documentation - this is already supported by using the end() method instead of close(). Unlike the close() method, the end() method will wait for all outgoing data to be sent and only then close() the socket resource.

I hope this helps 👍

Great, Thank you!
