SOCKET , TCP/IP Not working

Post by jaiswarvipin »

I ma developing on application for do the client server communication where my code is

Code: Select all

<?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 = '192.168.1.53';
$port = 10000;
$msg = "text"; 


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";
}

exit;
if (($ret = socket_listen($sock, 5)) < 0) {
    echo "socket_listen() failed: reason: " . socket_strerror($ret) . "\n";
}

exit;
do {
    if (($msgsock = socket_accept($sock)) < 0) {
        echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";
        break;
    }
    /* Send instructions. */
    //$msg = "\nWelcome to the PHP Test Server. \n" .        "To quit, type 'quit'. To shut down the server type 'shutdown'.\n";
	echo $msg;
    socket_write($msgsock, $msg, strlen($msg));

    do {
        if (false === ($buf = socket_read($msgsock, 2048, PHP_NORMAL_READ))) {
            echo "socket_read() failed: reason: " . socket_strerror($ret) . "\n";
            break 2;
        }
        if (!$buf = trim($buf)) {
            continue;
        }
        if ($buf == 'quit') {
            break;
        }
        if ($buf == 'shutdown') {
            socket_close($msgsock);
            break 2;
        }
        $talkback = "PHP: You said '$buf'.\n";
        socket_write($msgsock, $talkback, strlen($talkback));
        echo "$buf\n";
    } while (true);
    socket_close($msgsock);
} while (true);

socket_close($sock);
?>
above code gived me error "Warning: socket_bind() [function.socket-bind]: unable to bind address [0]: The requested address is not valid in its context. in D:\wamp\www\test.php on line 29"
but strage thing is that when i am using "Hercules" or any other 3rd part application to connent to server it worlk with any error and i am able to do the comunication with server.

Need help very ASAP?

That 192.168.1.53 ip - does it belong to the server running the script? *bind() requires local address.
