PHP Websocket Server hybi10 - php

Question

So Chrome 14 has implemented hybi10 version of websockets. I have a in house program that our company uses via chrome that uses websockets which is broken with this change.
Has anyone been successful framing the data using a php server? I am able to get the new handshake to work but I can't seem to figure out the framing. There is a python example here https://github.com/kanaka/websockify/blob/master/websocket.py#L233 but I am having a difficult time converting this to php, anyone have a suggestion?
I should mention that the function in question on the python example is decode_hybi().

Answer 1

i just completed a class wich makes the PHP-Websocket-Server of Nico Kaiser (https://github.com/nicokaiser/php-websocket) capable of handling hybi-10 frames and handshake. You can download the new class here: http://lemmingzshadow.net/386/php-websocket-serverclient-nach-draft-hybi-10/ (Connection.php)

Answer 2

This code assumes no errors or malformed frames and is based on this answer - How to (de)construct data frames in WebSockets hybi 08+?.
This code is very basic and is far from a complete solution. It works for my purposes (which are pretty basic). Hopefully it is of use to others.
function handle_data($data){
$bytes = $data;
$data_length = "";
$mask = "";
$coded_data = "" ;
$decoded_data = "";
$data_length = $bytes[1] & 127;
if($data_length === 126){
$mask = substr($bytes, 4, 8);
$coded_data = substr($bytes, 8);
}else if($data_length === 127){
$mask = substr($bytes, 10, 14);
$coded_data = substr($bytes, 14);
}else{
$mask = substr($bytes, 2, 6);
$coded_data = substr($bytes, 6);
}
for($i=0;$i<strlen($coded_data);$i++){
$decoded_data .= $coded_data[$i] ^ $mask[$i%4];
}
$this->log("Server Received->".$decoded_data);
return true;
}
Here is the code to send data back. Again this is pretty basic, it assumes you are sending a single text frame. No continuation frames etc. No error checking either. Hopefully others find it useful.
public function send($data)
{
$frame = Array();
$encoded = "";
$frame[0] = 0x81;
$data_length = strlen($data);
if($data_length <= 125){
$frame[1] = $data_length;
}else{
$frame[1] = 126;
$frame[2] = $data_length >> 8;
$frame[3] = $data_length & 0xFF;
}
for($i=0;$i<sizeof($frame);$i++){
$encoded .= chr($frame[$i]);
}
$encoded .= $data;
write_to_socket($this->socket, $encoded);
return true;
}
