Hi,

i've never used Socket's in a PHP Script before, but a quick look into the PHP Manual gave me a plenty amount of information about this.

Just look in the PHP Manual (downloadable from PHP.net in CHM Format, if you don't have it already) and look for "Socket Functions"

Short excerpt:

Socket creation:

<?php
$socket = stream_socket_server("tcp://0.0.0.0:8000", $errno, $errstr);
if (!$socket) {
 echo "$errstr ($errno)<br />\n";
} else {
 while ($conn = stream_socket_accept($socket)) {
   fwrite($conn, 'The local time is ' . date('n/j/Y g:i a') . "\n");
   fclose($conn);
 }
 fclose($socket);
}
?>

How to write to a socket and retrieve data:

<?php
$fp = stream_socket_client("tcp://www.example.com:80", $errno, $errstr, 30);
if (!$fp) {
   echo "$errstr ($errno)<br />\n";
} else {
   fwrite($fp, "GET / HTTP/1.0\r\nHost: www.example.com\r\nAccept: */*\r\n\r\n");
   while (!feof($fp)) {
       echo fgets($fp, 1024);
   }
   fclose($fp);
}
?>

Hope that helps,

Egon
