Hi - I have the same issue, althought I am using PHP 5.0RC3 (cli) from
Linux. Here is some of the code that I am using - I added an echo
statement so that I could see what was happening when I connected with
more than one client at a time:

$port = 5000;

if (!$sock = socket_create_listen($port)) {
   echo socket_strerror(socket_last_error());
}

if (!socket_set_option($sock, SOL_SOCKET, SO_REUSEADDR, 1)) {
   echo socket_strerror(socket_last_error());
}

if (!socket_set_nonblock($sock)) {
   echo socket_strerror(socket_last_error());
}

while   (true)
{
        $msgsock == FALSE;
        do
        {
                @$msgsock = socket_accept($sock);
        } while ($msgsock == FALSE);
        
   echo "Received connection from $msgsock\n";

Description:
------------
Hi to all

i'm tring to write a little application with PHP using Socket, the
external module, not fsockopen function or similar.

I've noticed that, with this, and previous version of php, that after i
create a socket and set it as non blocking socket, when i try to connect
using

socket_get_option($SOCKET, SOL_SOCKET, SO_ERROR)

i recive EVER 0
Instead i should recive 115
If socket_get_option, with these params, return 0, it mean that
connection is done and i can send datas, but if i send datas i get a
warning that say that socket is in a connection state so i can't send
datas.

There is some parts of code:
$this->socket[$sock_id]['resource'] = socket_create(AF_INET,
SOCK_STREAM, SOL_TCP);
if (!is_resource($this->socket[$sock_id]['resource']))
                                die("Unable to create socket! " .
socket_strerror(socket_last_error()) . "\r\n");
if (!socket_set_option($this->socket[$sock_id]['resource'], SOL_SOCKET,
SO_REUSEADDR, 1)) {
                                die("Unable to set to as REUSABLE socket! " .
socket_strerror(socket_last_error($this->socket[$sock_id]['resource']))
. "\r\n");
                        
after i set socket as reusable (but php gimme me the same problem
without this line too) and, after, if i need, i bind socket to a
specific IP and PORT

after there is this code:
                        @socket_connect($this->socket[$sock_id]['resource'],
$this->socket[$sock_id]['remote_host'],
$this->socket[$sock_id]['remote_port']);
while (($ris = @socket_get_option($this->socket[$sock_id]['resource'],
SOL_SOCKET, SO_ERROR)) == 115) {
        echo "--> " . $ris . "\r\n";
}
echo "\r\n--> " . $ris . "\r\n";

If you run this code it will exit immedatly printing:

--> 0

Infact, after, if you try to write to socket, you will get a warning

I haven't modified php.ini, and i've tried to run this code, using only
socket extension, on windows and on linux
I use apache 1.3.29 on windows and on linux

bye
