работает QTcpServer, как правильно получать или отправлять данные?

Я пытаюсь передать данные char из скрипта PHP на QTcpServer, и сервер получает соединение и также может ответить, но я не могу получить данные, которые отправил php.

Что я здесь не так делаю?

PHP-скрипт:

<?php

$addr = gethostbyname("127.0.0.1");

$client = stream_socket_client("tcp://$addr:51235", $errno, $errorMessage);

if ($client === false) {
throw new UnexpectedValueException("Failed to connect: $errorMessage");
}

$datatopost = 'a';
fwrite($client, $datatopost);
echo stream_get_contents($client);
fclose($client);
