Cliente/Server with PHP

[Dan]

Im trying to figure out the problem with a very simple client/server
program written in PHP.

Ill post the php code of the server and the client, both are based on
the annotated PHP Help.

The server will only write a message to a cliente every time one
connects to it.

Server Code:
<?
$direccion = '0.0.0.0';
$puerto = 4321;


if (($serverSocket = socket_create (AF_INET, SOCK_STREAM, 0)) < 0) {
echo socket_strerror ($serverSocket) . "\n";
}


if (($retorno = socket_bind ($serverSocket, $direccion, $puerto)) < 0)
{
echo socket_strerror ($retorno) . "\n";
}


if (($retorno = socket_listen ($serverSocket, 1)) < 0) {
echo socket_strerror ($retorno) . "\n";
}


do {
if (($cliente = socket_accept($ serverSocket)) < 0) {
echo socket_strerror ($cliente) . "\n";
break;
}
$mensaje = "bienvenido al server\n";
socket_write($c liente, $mensaje, strlen($mensaje ));



//socket_close ($msgsock);
} while (true);
socket_close ($sock);

?>

Client Code:
<?php
error_reporting (E_ALL);

echo "<h2>TCP/IP Connection</h2>\n";


$service_port = 4321;


$address = '127.0.0.1';

/* Create a TCP/IP socket. */
$socket = socket_create (AF_INET, SOCK_STREAM, 0);
if ($socket < 0) {
echo "socket_create( ) failed: reason: " . socket_strerror ($socket)
.. "\n";
} else {
echo "OK.\n";
}

echo "Attempting to connect to '$address' on port '$service_port' ...";
$result = socket_connect ($socket, $address, $service_port);
if ($result < 0) {
echo "socket_connect () failed.\nReason : ($result) " .
socket_strerror ($result) . "\n";
} else {
echo "OK.\n";
}


$out = '';


echo "Reading response:\n\n";
while ($out = socket_read ($socket, 2048)) {
echo $out;
}

echo "Closing socket...";
socket_close ($socket);
echo "OK.\n\n";
?>

Both pages are uploaded to the web, and both are in the same folder:
/server.php and /client.php. When I try to access the server page, it
stays waiting, and in a different client I try to access the client
page and it also stays waiting, without doing anything.

Anybody has any ideas what the problema is?
Thanks in advance,
