Thanks "loopfinity" . Your reply is appreciable, But still ..lemme show you with an example what I want..

In visual basic 6.0 I am using a socking, its coding is like:

Im sending packets like:
Socket1.SendData (0), HextoAscii("02 03 8E 00 1A 00 00 00 07 00 01 00 00 00 01 01")

Open in new window


Here (0) is the Array of the socket..


Same thing for Data Arrival method in vb6.0 is:

Private Sub Sockm_DataArrival(ByVal Index As Variant, ByVal bytesTotal As Long)
On Error Resume Next
Dim TempString as String

Socket1.GetData Index, TempString, vbString
If  TempString = "2 1 9C 0 Then
   msgbox "Login Successfully"
Else
  msgbox "Login Failed"
Endif

Open in new window



Same thing I wann do with the PHP sockets.. so please show me "How can I use above codings in PHP sockets"?

-Thanks alot in Advance..

Ok letme reduce the complexity of my question...

What should be the codings for : -

Suppose I wanna create a socket (TCP sockets not HTTP) with 5 arrays and wanna Connect these arrays with "gateway.abcdxyz.com" with Port "9009"

Now, After successfully connectivity , I wanna send a string to connected server.. string is "hello are you there?"

Now, If the connected server reply to my request, then I wanna display those responded message which are coming from the Server..
Example:
If server responding "Yes I am here"

then, how can I get responded message and can display it ?

-Thanks :(

Here is a basic client/server using the attached Socket.php class for the server

Running on your server:
<?php
require('Socket.php');

$my_socket = new Socket(100, 27, true);

while(!$my_socket->waitClient()) {
	sleep(100);
}

// now connected

$sent_text = $my_socket->read();

if (strlen($sent_text) > 0) {
	$my_socket->write("Yes I am here\n");
}

?>

Open in new window


connect on the client
<?php
ob_start();
$socket=socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
while (!socket_connect($socket, "localhost", 27)) {
	ob_flush();
	sleep(1);
}
$message="hello are you there?\n";
$sent = socket_write($socket, $message);
if ($sent === false) {
	// Error occurred, break the while loop
	echo "error";
	break;
}
else {
	// Data sent ok
	echo "sent: $message<br/>";
	echo "received: " . read($socket);
}
ob_end_flush();

function read($_socket) {
	$message = '';
	do {
		$buff     = socket_read($_socket,1,PHP_BINARY_READ);
		$message .= $buff;
	} while( $buff != "\n" );
	return $message;
}
?>

Open in new window

Socket.php
