PHP Code:

function pluralize($word,$var){
    if($var!=1){
        $word = $word."s";
    }
    if($var>0){
        $word = $var." ".$word." ";
    }else{
        $word = "";
    }
    return $word;
}
function timediff($earlier,$later){
    $secs = $earlier - $later; 
    $string="";
    if($secs>=604800){
        $weeks = 0;
        while($secs>=604800){
            $secs -= 604800;
            $weeks++;
        }
        $string .= pluralize("week",$weeks);
    }
    if($secs>=86400){
        $days = 0;
        while($secs>=86400){
            $secs -= 86400;
            $days++;
        }
        $string .= pluralize("day",$days);
    }
    if($secs>=3600){
        $hours = 0;
        while($secs>=3600){
            $secs -= 3600;
            $hours++;
        }
        $string .= pluralize("hour",$hours);
    }
    if($secs>=60){
        $minutes = 0;
        while($secs>=60){
            $secs -= 60;
            $minutes++;
        }
        $string .= pluralize("minute",$minutes);
    }
    return $string;
} 


There are the functions anyway, you would use like this:

PHP Code:

$variable = timediff(time(),$userlastvisit); 


with $userlastvisit being the field 'lastvisit' pulled from the user table from the row of the corresponding member. Then, just add $variable in any of your templates and it will return a string something like "1 day 3 hours 12 minutes", or "2 weeks 8 hours 1 minute". Let me know where you would want this information displayed, and I'll write and release a full fledged hack for it.
