Bon voila, j'a un petit souci.
Je voudrais envoye et recevoir, a la maniere d'un server, des données a une machine x.
Les sockets ca doit pouvoir permettre de la faire. Mais je debute : je vais voir dans les manuels, je trouve ce script:

<?php
error_reporting (E_ALL);
/* Allow the script to hang around waiting for connections. */
set_time_limit (0);
/* Turn on implicit output flushing so we see what we're getting
* as it comes in. */
ob_implicit_flush ();
$address = '127.0.0.1';
$port = 80;
if (($sock = socket_create(AF_INET, SOCK_STREAM,SOL_TCP)) < 0)
{
echo "socket_create() failed: reason: " . socket_strerror($sock) . "\n";
}
if (($ret = socket_bind($sock,address ,$port )) < 0)
{
echo "socket_bind() failed: reason: " . socket_strerror($ret) . "\n";
}
if (($ret = socket_listen($sock, 10)) === false)
{
echo "socket_listen() failed: reason: " . socket_strerror($ret) . "\n";
}
do
{
if (($msgsock = socket_accept($sock)) === false)
{
echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";
break;
}
/* Send instructions. */
$msg = "\n Welcome to the PHP Test Server. \n\r" .
"To quit, type 'quit'. To shut down the server type 'shutdown'.\n\r";
socket_write($msgsock, $msg, strlen($msg));
$cmd = "";
do {
if (false === ($buf = socket_read($msgsock, 4096)))
{
echo "socket_read() failed: reason: " . socket_strerror($ret) . "\n";
break 2;
}
if ($buf == "\r\n")
{
if ($cmd == 'm00')
{
socket_write($msgsock, "PHP replies: Must be a cow out there...\n\r", strlen ("PHP replies: Must be a cow out there... "));
}
if ($cmd == 'quit')
{
socket_write($msgsock, "\n\rClosing connection ...", strlen (" Closing connection ..."));
break;
}
if ($cmd == 'shutdown')
{
socket_write($msgsock, "\n\rShutdown initiated...", strlen (" Shutdown initiated..."));
socket_close ($msgsock);
break 2;
}
$cmd = "";
}
else
{
$cmd .= $buf;
}
} while (true);
socket_close ($msgsock);
} while (true);
socket_close ($sock);
?>

comment le configurer de telle maniere qu'il marche :
lorsque je lance ce code, l'erreur suivante apparait
Warning: socket_bind() unable to bind address [0]: Only one usage of each socket address (protocol/network address/port) is normally permitted. in c:\program files\easyphp1-8\www\index.php on line 16
socket_bind() failed: reason: The operation completed successfully.
Warning: socket_listen() unable to listen on socket [0]: An invalid argument was supplied. in c:\program files\easyphp1-8\www\index.php on line 21

Warning: socket_accept() unable to accept socket connection [0]: The operation completed successfully. in c:\program files\easyphp1-8\www\index.php on line 27

evidemment, je m'y prend peut etre mal, voire tres mal. Mais excuser ma debutante attitude.

Merci de m'aider
