No data returned from server written to socket before connection close

[pitersky]

Hi!

I have a following code

$socket->on('connection', function ($conn) 
{
  $conn->write("Hello there!\n");

  $conn->on('data', function ($data) use ($conn) {
    $conn->write("I have received a data!\n");
    $conn->close();
  });
});

The problem is I only receive "Hello there" string, but not "I have received a data!\n". I am not receiving second string even with sleep(5) or something before $conn->close() line. Is this a bug or I am doing something wrong?

Thank you in advance.

PS

comoser:

{
    "require": {
        "react/socket": "~0.4.0"
    }
}

close immediately closes the socket. Being an asynchronous environment that could happen before the write happens. Instead, use $conn->end(). That will close the connection after the write buffer has been drained.

->end() works great, thank you!
