[SOLVED] php socket_server. Disconnecting client problem

[zaez]

Alright i'm running my server on my localip, accesible only for our network.

the loop:

^{private function listenToSockets()}

^{

 

^{while (true) {}

 

^{$changed_sockets = $this->currentSockets;}

 

^{$num_changed_sockets = socket_select($changed_sockets, $write = NULL, $except = NULL, NULL);}

 

^{foreach($changed_sockets as $socket)}

^{

^{if ($socket == $this->masterSocket)}

^{

^{if (($client = socket_accept($this->masterSocket)) < 0) {}

^continue;

^}

^else

^{

 

^{// NEW CLIENT HAS CONNECTED}

^{$this->currentSockets[] = $client;}

^{socket_getpeername($client, $newClientAddress);}

^}

^}

^else

^{

^{$bytes = socket_recv($socket, $buffer, 4096, 0);}

^{if ($bytes == 0)}

^{

 

^{// CLIENT HAS DISCONNECTED}

^{$index = array_search($socket, $this->currentSockets);}

 

^{// Remove Socket from List}

^{unset($this->currentSockets[$index]);}

 

^{$this->game->removePlayer($socket);}

 

^{socket_close($socket);}

 

^}

^else

^{

 

^{// CLIENT HAS SENT DATA}

^{$this->parseRequest($socket, $buffer);}

^}

^}

^}

^}

^}

 

the client side is AS3, connecting through XMLSocket, and talking to the server using XML data.

 

Well everything works good. The problem is that if i disconnect the client from the network (unpluging the cable, or just disconnecting the wireless connection), this:

 

^{if ($bytes == 0)}

^{

 

^{// CLIENT HAS DISCONNECTED}

^{$index = array_search($socket, $this->currentSockets);}

 

^{// Remove Socket from List}

^{unset($this->currentSockets[$index]);}

 

^{$this->game->removePlayer($socket);}

 

^{socket_close($socket);}

 

^}

won't trigger, as if the socket would be still sending data.

 

So, question:

How do i make my server script detect when a client disconnects from the network?

Any help, or advices welcome and appreciated.

Thank you for looking!
