I've looked in to this a bit but still don't really understand if its possible.

I have a small webserver that sits on my private network. I want to create a php script that will connect to a telnet server on the private network and send it text every 30 seconds.

Obviously the easy part is the text and timing but connection to a TCP Port 23 and sending a string of text seems harder for some reason. What's the best way to do this?

    Use PHP sockets :

        sleep 30;
        $fp = fsockopen("", 23, $errno, $errstr, 30);
        if (!$fp) {
            echo "$errstr ($errno)<br />
        } else {
            fwrite($fp, "The string you want to send");
            while (fgets($fp, 128)) {
                echo fgets($fp, 128); // If you expect an answer
            fclose($fp); // To close the connection
