Undefined index: Sec-WebSocket-Key for wss connection

[factorin-j]

I'm unable to connect to the socket server if the client is changed to wss and accessed via https

PHP Notice:  Undefined index: Sec-WebSocket-Key in /path/to/repository/server.php on line 140

$headers = array();
    $lines = preg_split("/\r\n/", $receved_header);
    foreach($lines as $line)
    {
        $line = chop($line);
        if(preg_match('/\A(\S+): (.*)\z/', $line, $matches))
        {
            $headers[$matches[1]] = $matches[2];
        }
    }

    $secKey = $headers['Sec-WebSocket-Key']; // This line giving error.

Please fix this

@factorin-j @varun-naharia theirs a server code update to use: stream_socket_server() see here> https://www.php.net/manual/en/function.stream-socket-server.php#125540 this fixes ssl/https but also since ive adapted my code i no longer get these errors
