time_since() HELP ON WEEKS!

[iantearle]

Hey everyone, been working on this time_since() for a while, basically want it to have the ability to put phrases instead of just time in days, minutes etc, for example if it was less than 30 seconds ago, i would want it to say, "saved a moment ago"

 

here is what i have so far, works great up until weeks! then it just buggers up and doesnt show it weeks, only days!

 

HELP!

        $now = time(); 

    $diff = $now - $mbtime;

/* Convert PHP time/date to legiable data, to do the math */ 
    $today = date('dmy', $now) === date('dmy', $mbtime) ? true : false; 
    
if($today && $diff < 10){ // if less than 10 seconds ago
	$num = ceil($diff / 60); 
	return 'a moment ago'; 
    }
