Hi Christian,

Found a "memory leak" in my local server using this component and isolated it to this class+method. The memory usage keeps growing indefinitely as more messages are passed to the WriteMessage() method as it never trims its internal arrays (both the bufferedData and bufferedType arrays can grow indefinitely large.)

Here is a new implementation from clue for basic sse support with the new components.

Im only dumping this here because this repo is the first result on google.

This component uses outdated Http and deprecated SocketClient which has been replaced by Socket. Updating this will involve a BC break to the API.

Opening this ticket for the reference and will address this soon-ish.

I'm testing out react with addition of clue/php-sse-reactt, but can't make it work properly.
I'm using server like in the example:

require __DIR__ . '/../vendor/autoload.php';

use Clue\React\Sse\BufferedChannel;
use React\Http\Request;
use React\Http\Response;


$loop = React\EventLoop\Factory::create();
$socket = new React\Socket\Server($loop);

$channel = new BufferedChannel();

$http = new React\Http\Server($socket);

$http->on('request', function (Request $request, Response $response) use ($channel) {
    echo 'connected' . PHP_EOL;

    $headers = $request->getHeaders();
    $id = isset($headers['Last-Event-ID']) ? $headers['Last-Event-ID'] : null;

    $response->writeHead(200, array('Content-Type' => 'text/event-stream', 'Cache-Control' => 'no-cache'));
    $channel->connect($response, $id);

    $response->on('close', function () use ($response, $channel) {
        echo 'disconnected' . PHP_EOL;
        $channel->disconnect($response);
    });
});

$loop->addPeriodicTimer(2.0, function() use ($channel) {
    $channel->writeMessage('ticking ' . mt_rand(1, 5) . '...');
});

$socket->listen(1337);

echo 'Server now listening on localhost:' . $socket->getPort() . PHP_EOL;
$loop->run();

Than I run it with bash: $ php server.php

When I'm doing script:
var eventSource = new EventSource('server.php');

it gives an error:
EventSource's response has a MIME type ("text/html") that is not "text/event-stream". Aborting the connection.
What might be the problem?

Also I used
$ echo -e "GET / HTTP/1.0\r\n\r\n" | nc localhost 1337
and it returned

HTTP/1.1 200 OK
X-Powered-By: React/alpha
Content-Type: text/event-stream
Cache-Control: no-cache
Transfer-Encoding: chunked

I was using Clue\React\Sse\BufferedChannel and it was working fine (as in example 11-chat.php.
Now apparently it was substituted by clue/sse-react, but I get an error on composer:
composer require clue/sse-react
