PHP Proxy -- Passing FORM DATA (Part 2): fputs, phpbb, login

PHP Proxy -- Passing FORM DATA (Part 2)

Code:

<?

// http.inc by nf@bigpond.net.au
// http://nf.wh3rd.net/

function http_post($server, $port, $url, $vars) {

// example:
// http_post(
//      "www.fat.com",
//      80,
//      "/weightloss.pl",
//      array("name" => "obese bob", "age" => "20")
//      );

      $user_agent = "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)";

      $urlencoded = "";
      while (list($key,$value) = each($vars))
            $urlencoded.= urlencode($key) . "=" . urlencode($value) . "&";
      $urlencoded = substr($urlencoded,0,-1);

      $content_length = strlen($urlencoded);

      $headers = "POST $url HTTP/1.1
Accept: */*
Accept-Language: en-au
Content-Type: application/x-www-form-urlencoded
User-Agent: $user_agent
Host: $server
Connection: Keep-Alive
Cache-Control: no-cache
Content-Length: $content_length

";

      $fp = fsockopen($server, $port, $errno, $errstr);
      if (!$fp) {
            return false;
      }

      fputs($fp, $headers);
      fputs($fp, $urlencoded);

      $ret = "";
      while (!feof($fp))
            $ret.= fgets($fp, 1024);

      fclose($fp);

      return $ret;

}

echo http_post("www.server.com", 80, "/phpBB2/login.php", array("username" => "test", "password" => "12345", "login" => "Login"));

?>

After help getting going on POSTing form data through a proxy written in PHP, I found this bit of code. I'm using it to log in to a phpBB board and the login is successful. The problem I've run into is that what is returned by the statement

return $ret;

is the header for the page that the phpBB login page redirects to (index.php). I need help figuring out how to continue the communication between the client and the server. I need to be able to pass cookie information back and forth to maintain the logged in state.
