need help in Socket programming

[jawainc]

Hi

i'm new to php. having some problems here is what i'm doing

 

this is the server file

 

index.php

 

<?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;
echo $address;
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
   echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}

if (socket_bind($sock, $address) === false) {
   echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}

if (socket_listen($sock, 5) === false) {
   echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}

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

   do {
       if (false === ($buf = socket_read($msgsock, 2048, PHP_NORMAL_READ))) {
           echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n";
           break 2;
       }
       if (!$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);
echo $address;
echo $port;
socket_close($sock);
?> 

 

 

 

and the client side file

 

clinet.php

 

<?php
error_reporting(E_ALL);

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

// Get the port for the WWW service. 
$service_port = getservbyname('http', 'tcp');
//echo $service_port;
// Get the IP address for the target host. 
$address = gethostbyname('localhost');

// Create a TCP/IP socket. 
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
   echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
} else {
   echo "socket created <br>OK<br />";
}

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

$in = " GET / HTTP:/1.1\r\n";
$in .= "Host: localhost/index.php\r\n";
$in .= "Connection: Close\r\n\r\n";
$out = '';
echo '****'.$in.'***<br>';
echo "Sending HTTP HEAD request...<br>";
socket_write($socket, $in, strlen($in));
echo "OK<br>";

echo "Reading response:\n\n<br>";
while ($out = socket_read($socket, 2048)) {
   echo '************<br>'.$out.'<br>*************<br>';
}

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

?>

 

when i run the file i got following error

 

 

TCP/IP Connection

Attempting to connect to '127.0.0.1' on port '80'...socket connect

1) Your client script is connecting to Apache instead of your server script. Use a different pot or stop the Apache service.

 

2) Your HTTP HEAD is malformed. Try losing the colon; "GET / HTTP/1.1\r\n".
