Got a bit of a dilema with a script I've been working on for some time now.... It works 100% other than the fact that it can only accept ONE stinking connection at a time. In fact, a second "attempt" by another client will crash the script.
Anyway, I'm relatively sure I'll need to fork the process, from what I've read, but after about 4 hours of failed attempts at doing so... HELP!

socket_close ($sock);
exit("\nReceived authorized shutdown command. Sockets Closed.");
}
if (strstr($waitfor,"quit"))
{
socket_close ($msgsock);
socket_close ($sock);
break;
}
// ... various other commands & responses
}
} while(true);
} while(true);
exit;
?>
Not sure just how many sockets one can effectively manage with a single instance of the script invoked... but hopefully someone here a bit more familiar with sockets / forks will be able to shed some much needed light on my little project....
Thanks
