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

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
