[Resolved] socket

Hi,
I have got the following script which connects to a server program that I have scripted in c++. I want the php script to send commands to the program and it is doing that. However I dont think the php is sending the data correctly as although the server says it has recieved the data it is not proccessing it correctly. I know this is not the server itself as I can connect to it via telnet and it when I send the command it all works properly. So is their either a more specific way of connecting to telnet in php or is there something that I need to change in my php code?

<?php
   $server = "127.0.0.1";
   $port = "20248";
   $data = "STOP";
   $connection = fsockopen($server, $port, $errno, $errstr, 30);

   if(!$connection) {
       print "Connect Failed: $errstr ($errno)";
   } else {
       $output = fgets($connection, 20248);
       fputs($connection, "$data\n");
}
?>

Could it be the line ending? You currrently use a LF, perhaps it's looking for a CRLF ending instead?

Also, perhaps you are trying to read input too soon? Try switching the order of commands, like so:

   } else { 
       fputs($connection, "$data\n");
       $output = fgets($connection, 20248); 
}

Just wondering what do you mean by the LF and a CRLF and how could I change it?

Thanks.

Nevermind I found out what the problem was. It wasnt working because of the \n on the data. Thanks for trying to help anyway 🙂
