in that case, the documentation on socket_select() needs to be edited:

http://www.php.net/socket-select says:

<?php
/* Prepare the read array */
$read = array($socket1, $socket2);

$num_changed_sockets = socket_select($read, $write = NULL, $except = NULL,
0);

if ($num_changed_sockets === false) {
   /* Error handling */
} else if ($num_changed_sockets > 0) {
   /* At least at one of the sockets something interesting happened */
}
?>

according to you, $write and $except could be undefined, right?
