socket_select worries

[Craigles1981]

Hi There,

I've managed to fix the timeout problem I mentioned in a previous request, however I'm now having a different problem.

Whenever I use the below peice of code in my program, and then exit it throws up the following error:

PHP Warning: socket_select() unable to select [4]: Interrupted system call in /home/craigm/spam/spamterminator.php on line 46

Can somebody tell me what is wrong with it, or even perhaps an explanation upon what that error message actually means.

Thanks,

Craig Marchant

---- code snippet -----

// Loop through socket_select until activity detected, then accept connection
while ( true ) {

/ Prepare the read array /
$read = array($sock);

if (false === ($num_changed_sockets = socket_select($read, $write = NULL, $except = NULL, 10))) {
continue;
} else if ($num_changed_sockets > 0) {
AcceptIncommingConnection();
break;
}
}
