Hello,
Does anyone have any experience with phpwebsocket by google?
I'm having a problem connecting to my server... Here is the two files:
(server.php)
#!/php -q
<?php /* >php -q server.php */
error_reporting(E_ALL);
set_time_limit(0);
ob_implicit_flush();
$master = WebSocket("[server_IP]",12345);
$sockets = array($master);
$users = array();
$debug = false;
while(true){
$changed = $sockets;
socket_select($changed,$write=NULL,$except=NULL,NULL);
foreach($changed as $socket){
if($socket==$master){
$client=socket_accept($master);
if($client<0){ console("socket_accept() failed"); continue; }
else{ connect($client); }
}
else{
$bytes = @socket_recv($socket,$buffer,2048,0);
if($bytes==0){ disconnect($socket); }
else{
$user = getuserbysocket($socket);
if(!$user->handshake){ dohandshake($user,$buffer); }
else{ process($user,$buffer); }
}
}
}
}
//---------------------------------------------------------------

say("< ".$action);
switch($action){
