Change time and date to "2 month 3 days"

Hi,
I currently have this function and it gives me "2 months ago" if the date is = Febuary 6th 2009, but I also want it to add the words "2 months ago 3 days"

Also is this the best way to do it, or is it resource intensive?

if(!function_exists('how_long_ago')){
        function how_long_ago($timestamp){
            $difference = time() - $timestamp;

            if($difference >= 60*60*24*365){        // if more than a year ago
                $int = intval($difference / (60*60*24*365));
                $s = ($int > 1) ? 's' : '';
                $r = $int . ' year' . $s . ' ago';
            } elseif($difference >= 60*60*24*7*5){  // if more than five weeks ago
                $int = intval($difference / (60*60*24*30));
                $s = ($int > 1) ? 's' : '';
                $r = $int . ' month' . $s . ' ago';
            } elseif($difference >= 60*60*24*7){        // if more than a week ago
                $int = intval($difference / (60*60*24*7));
                $s = ($int > 1) ? 's' : '';
                $r = $int . ' week' . $s . ' ago';
            } elseif($difference >= 60*60*24){      // if more than a day ago
                $int = intval($difference / (60*60*24));
                $s = ($int > 1) ? 's' : '';
                $r = $int . ' day' . $s . ' ago';
            } elseif($difference >= 60*60){         // if more than an hour ago
                $int = intval($difference / (60*60));
                $s = ($int > 1) ? 's' : '';
                $r = $int . ' hour' . $s . ' ago';
            } elseif($difference >= 60){            // if more than a minute ago
                $int = intval($difference / (60));
                $s = ($int > 1) ? 's' : '';
                $r = $int . ' minute' . $s . ' ago';
            } else {                                // if less than a minute ago
                $r = 'moments ago';
            }

            return $r;
        }
    }

is this possible

 

"Is this possible?" Frightens me about the future of the human race that someone would even phrase such a question. Think about it. Assuming you're willing to pretend a month is 30 days (which you seem to be), then:

$months = floor($difference / 30);
$days = $difference - ($months * 30);
