Based upon the second example on
http://www.php.net/manual/en/ref.sockets.php
:
echo "<h2>TCP/IP Connection</h2>\n";
/* Get the service for TCP-Port 25. */
$service_port = getservbyport (25, 'tcp');
/* Get the IP address for the target host. */
$address = gethostbyname ('www.example.com');
/* 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";
}
