Approximate date

[tail]

I'm currently using a function to change my dates to more a more readable format such as "3 hours ago" or "9 months ago". However, if the date given is 9 months and one week ago, it will only output "9 months ago". Can someone help me edit the function I'm using? Here's the function I'm currently using:

function nicetime($date)

{

	if(empty($date)) {

		return "No date provided";

	}

	$periods         = array("second", "minute", "hour", "day", "week", "month", "year", "decade");

	$lengths         = array("60","60","24","7","4.35","12","10");

	$now             = time();

	$unix_date         = strtotime($date);

	   // check validity of date

	if(empty($unix_date)) {   

		return "Bad date";

	}

	// is it future date or past date

	if($now > $unix_date) {   

		$difference     = $now - $unix_date;

		$tense         = "ago";						   

	} else {

		$difference     = $unix_date - $now;

		$tense         = "from now";

	}					   

	for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) {

		$difference /= $lengths[$j];

	}					   

	$difference = round($difference);					   

	if($difference != 1) {

		$periods[$j].= "s";

	}					   

	return "$difference $periods[$j] {$tense}";

}

Thank you! But is there a way to only show the two greatest times? And if the time is less than one week, just output the number of days instead of the two greatest times? Such as "2 days ago", "6 hours ago", "1 week, 3 days ago",  or "9 months, 2 weeks ago".
