Counting down years, weeks, days, etc

[tail]

I'm trying to make a countdown to show the amount of time between two dates, however when the script starts calculating days it screws up and says the actual amount of days between the two and not the days leftover after calculating years and weeks. Here is my code:

 

$years_left = floor($difference/60/60/24/365).' years';
$weeks_left = floor(($difference - $years_left*60*60*24*365)/60/60/24/7).' weeks';
$days_left = floor(($difference - $weeks_left*60*60*24*7)/60/60/24).' days';
$hours_left = floor(($difference - $days_left*60*60*24)/60/60).' hours';
$minutes_left = floor(($difference - $hours_left*60*60)/60).' minutes';

Any help is much appreciated!

if you use "%" it will give you what is left over after division is done...

I'm not sure I understand what you're saying. I've never used modulus before. Should I replace the division signs with a % like this:

 

$years_left = floor($difference%60%60%24%365).' years';
$weeks_left = floor(($difference - $years_left*60*60*24*365)%60%60%24%7).' weeks';
$days_left = floor(($difference - $weeks_left*60*60*24*7)%60%60%24).' days';
$hours_left = floor(($difference - $days_left*60*60*24)%60%60).' hours';
$minutes_left = floor(($difference - $hours_left*60*60)%60).' minutes';

[The Little Guy]

yeah, see what it gives you.

[tail]

$difference = (1241746582+34667326)-time();
$years_left = floor($difference%60%60%24%365).' years';
$weeks_left = floor(($difference - $years_left*60*60*24*365)%60%60%24%7).' weeks';
$days_left = floor(($difference - $weeks_left*60*60*24*7)%60%60%24).' days';
$hours_left = floor(($difference - $days_left*60*60*24)%60%60).' hours';
$minutes_left = floor(($difference - $hours_left*60*60)%60).' minutes';

 

output: 13 years -2 weeks 13 days 13 hours 13 minutes

 

it returns a different output each time.

That seems like a little much to do what I'm trying to do. Is there any way to accomplish this task the way I am?

[premiso]

Sorry I did miss the "between" part.

Maybe more of the function for you. As far as it being a little much, I think you are underestimating what you are wanting to do.

Talk about confusing! Please use mktime. It's better than hard coding those huge numbers.

 

Why do you have weeks but *not* months? That's stupid.

 

Your math is a bit off. Since years have no restrictions, calculate how many years it would take. Then subtract the time from $difference. Next, calculate the number of weeks, but remember that weeks can never be more than 52 because that would equal a year. Though if you did it right, you should not get 52. For days, it should be same math except you have to restrict it down to only 6 days or less because more than that would be a week. Get it?

 

I suggest you start over from a fresh mind. You're too caught up to think straight with that messy glob.

Thanks for the help everyone. And for the idea of using mktime(), ken2k7.

 

New code:

$until = $r['time']+$r['length'];
$time = mktime(date('G',$until),date('i',$until),date('s',$until),date('n',$until),date('j',$until),date('Y',$until)) - time();
$years = floor($time/31536000).' years,';
$months = floor(($time-($years*31536000))/2628000).' months,';
$weeks = floor(($time-($years*31536000)-($months*2628000))/604800).' weeks';
$days = floor(($time-($years*31536000)-($months*2628000)-($weeks*604800))/86400).' days';
$hours = floor(($time-($years*31536000)-($months*2628000)-($weeks*604800)-($days*86400))/3600).' hours';
$minutes = floor(($time-($years*31536000)-($months*2628000)-($weeks*604800)-($days*86400)-($hours*3600))/60).' minutes';

Instead of doing the math over and over, why not just subtract from time?

[tail]

What do you mean?

Look at your code. You have a bunch of $years * 31536000 and $months * 2628000 etc in your math. You're making the computer re-calculate those values every time. It does it fast, but I think it's better to just save that in a variable so it doesn't have to keep multiplying the same numbers over and over again. Same for the subtraction. Get it now?
