Adding commas question

[Boofo]

Here is the code I am currently using, but as you can see there is an extra comma after the room names. It happens with more than one user, too. That's why I thought with fresh code as above, it might be easier to do the commas right.

PHP Code:

$port = 10010;
function getServerAPI($apiCommand)
{
    global $port;
    $result = "";
    $fp = fsockopen("localhost", $port, &$errno, &$errstr, 2);
    if(!$fp)
    {
        echo "$errstr ($errno)\n";
    }
    else
    {
        fputs($fp,"GET /?".$apiCommand." HTTP/1.0\n\n");
        $header = true;
        while(!feof($fp))
        {
            $line = fgets($fp,128);
            // print $line;
            if ($header == false)
   if($apiCommand!='api.UserList') {
   $result .= trim($line) . ', ';
   }else {
   $result .= substr($line, 0, -1); // trim the last ', '
   }
            if (trim($line) == "")
                $header = false;
        }
        fclose($fp);
    }
    return substr($result, 0, -2); // trim the last ', '
}
$userCount = getServerAPI( "api.UserList" );
$roomList = getServerAPI( "api.RoomList" ); 


This is what it looks like after we get the roomlist and the userlist. If you need to see the template, let me know.
