Help with porting over latest postid/threadid

[freakyshiat]

I need to port over the latest threadid/postid on index page from 3.0.x to 3.5.x. The code below worked fine in 3.0.x, can someone help me port it to 3.5.x? I can via paypal, please pm me.

$newestthreadidq = $DB_site->query("
                                SELECT threadid
                                FROM thread
                                ORDER BY threadid DESC
                                LIMIT 1
                                ");
$newestthreadid = $DB_site->fetch_array($newestthreadidq);
$newestpostidq = $DB_site->query("
                                SELECT postid
                                FROM post
                                ORDER BY postid DESC
                                LIMIT 1
                            ");
$newestpostid = $DB_site->fetch_array($newestpostidq);
$formattedthreadid = number_format($newestthreadid[threadid]);
$formattedpostid = number_format($newestpostid[postid]);
