I am experimenting with php and listening on port's i got this script from http://www.php.net/manual/en/function.socket-select.php#56241

#!/usr/bin/php
<?php

$port = 9050;

// create a streaming socket, of type TCP/IP
$sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) or die('ERROR 1');

// set the option to reuse the port
socket_set_option($sock, SOL_SOCKET, SO_REUSEADDR, 1) or die('ERROR 1');

// "bind" the socket to the address to "localhost", on port $port
// so this means that all connections on this port are now our resposibility to send/recv data, disconnect, etc..
socket_bind($sock, 0, $port) or die('ERROR 1');

// start listen for connections
socket_listen($sock) or die('ERROR 1');

// create a list of all the clients that will be connected to us..
// add the listening socket to this list
$clients = array($sock);
while (true) {

// create a copy, so $clients doesn't get modified by socket_select()
$read = $clients;

// get a list of all the clients that have data to be read from
// if there are no clients with data, go to next iteration
if (socket_select($read, $write = null, $except = null, 0) < 1)
	continue;

// check if there is a client trying to connect
if (in_array($sock, $read)) {
	// accept the client, and add him to the $clients array
	$clients[] = $newsock = socket_accept($sock);

	// send the client a welcome message
	socket_write($newsock, "no noobs, but ill make an exception \n" . "There are " . (count($clients) - 1) . " client(s) connected to the server\n");

	socket_getpeername($newsock, $ip);
	echo "New client connected: {$ip}\n";

	// remove the listening socket from the clients-with-data array
	$key = array_search($sock, $read);
	unset($read[$key]);
}

// loop through all the clients that have data to read from
foreach ($read as $read_sock) {
	// read until newline or 1024 bytes
	// socket_read while show errors when the client is disconnected, so silence the error messages
	$data = @socket_read($read_sock, 1024, PHP_NORMAL_READ);

	// check if the client is disconnected
	if ($data === false) {
		// remove client for $clients array
		$key = array_search($read_sock, $clients);
		unset($clients[$key]);
		echo "client disconnected.\n";
		// continue to the next client to read from, if any
		continue;
	}

	// trim off the trailing/beginning white spaces
	$data = trim($data);

	// check if there is any data after trimming off the spaces
	if (!empty($data)) {

		// send this to all the clients in the $clients array (except the first one, which is a listening socket)
		foreach ($clients as $send_sock) {

			// if its the listening sock or the client that we got the message from, go to the next one in the list
			if ($send_sock == $sock || $send_sock == $read_sock)
				continue;

			// write the message to the client -- add a newline character to the end of the message
			socket_write($send_sock, $data . "\n");

		} // end of broadcast foreach

	}

} // end of reading foreach
}

// close the listening socket
socket_close($sock);
?>

but when i telnet into this script nothing happens.

the script gets no errors i am using localhost to check it.

i don't want a chat script but i want to make this one work so i can use it to build something else.

 

Scott.
