[SOLVED] Multiple sockets

[mcky]

Hello,

 

Basically I'm very new to PHP and am trying to write an IRC bot that will also listen to a game server. I can get both sockets to work fine individually, but I don't know how to have them work simultaneously (ie. something is triggered by the game server socket, and then a command is sent to the IRC socket).

 

These are cut down versions of each socket:

 

$socket = stream_socket_server('udp://123.456.789:1234', $errno, $errstr, STREAM_SERVER_BIND);
if ($socket) {
    while (!feof($socket)) {
    $data = stream_socket_recvfrom($socket, 4096);
    /* Do stuff */
    }
    fclose ($connection);
} else {
    print "Unable to connect!\n";
}

 

$con = array();
init();

function init()
{
        global $con, $CONFIG;
        $con['socket'] = fsockopen($CONFIG['server'], $CONFIG['port']);

        if (!$con['socket']) {
                print ("Could not connect to: ". $CONFIG['server'] ." on port ". $CONFIG['port']);
        } else {
                while (!feof($con['socket']))
                {
                        $con['buffer']['all'] = trim(fgets($con['socket'], 4096));
                        /* Do stuff */
                }
        }
}

 

Can anyone help me out/point me in the right direction?

 

Thanks

you could open both sockets then run a while loop with while(true) and inside do !fefo checks with two if statements on for each socket

I managed to get that method working for two UDP sockets (a duplicate of $socket) but I can't seem to get it to work with the IRC socket.

I guess what I'm asking is if someone could show me an example using the code I gave in the first post.

This is what I've come up with so far.

 

                $irc = fsockopen($CONFIG['server'], $CONFIG['port']);
                $socket = stream_socket_server('udp://123.456.789:12341', $errno, $errstr, STREAM_SERVER_BIND);
                if (!$irc) {
                        print ("Could not connect to: ". $CONFIG['server'] ." on port ". $CONFIG['port']);
                } else {
                /* Initial info for the IRC server */
                        cmd_send("USER ". $CONFIG['nick'] ." nothing nothing :". $CONFIG['name']);
                        cmd_send("NICK ". $CONFIG['nick'] ." nothing");
                }

while (true) {

                if (!feof($socket)) {
                       $data = stream_socket_recvfrom($socket, 4096);
                        echo "1".$data;
                        unset($data);
                }
                if (!feof($irc))
                {
                       $con['buffer']['all'] = trim(fgets($irc, 4096));
                }
                else {
                /* Nothing yet */
                }
}

 

If I comment out the if (!feof($socket)) statement, it connects to the IRC server fine, but as soon as I leave it in, the script just hangs.

 

Can anyone help?

I've realised that the sockets do work as long as there is data coming for both. If one socket isn't receiving any data, the other socket hangs as well. Is there a simple way to fix this?

php doesn't support threading (asynchronous processing).  Google "php forking"

Well that was surprisingly easy. Thanks Crayon Violent.
