Default Basilar problems in programmming with socket

Hi everyone,
first of all sorry for my bad English
I've started programming with socket in php (yes, I'm a newbie) and I've already a problem which doesn't allow me to go forward.
Hope you can help me...
I've tried to use the entire code token from the article called 'Socket Programming With PHP' but it doesn't work properly under win xp.
It comes out this error
-- Warning: socket_bind() unable to bind address [10048]: Di norma è consentito un solo utilizzo di ogni indirizzo di socket (protocollo/indirizzo di rete/porta). in c:\programmi\apache group\apache\htdocs\test\socket\socket.php3 on line 14
Could not bind to socket

Total translation should be:
-- Warning: socket_bind() unable to bind address [10048]: basely it is allowed a unique address of socket (protocol/network address/port). in c:\programmi\apache group\apache\htdocs\test\socket\socket.php3 on line 14
Could not bind to socket

Here the configuration: apache/1.3.27 (Win32) PHP/4.3.4

Here the code:
--- socket.php3 ---

// set some variables
$host = "";
$port = 1234;

// don't timeout!

// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create

// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to

// start listening for connections
$result = socket_listen($socket, 3) or die("Could not set up socket

// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming

// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");

// clean up input string
$input = trim($input);

// reverse client input and send back
$output = strrev($input) . "\n";
socket_write($spawn, $output, strlen ($output)) or die("Could not write

// close sockets

Thanks a lot to all in advance!
