the time that is left until the date reaches 24 hours

[fr8]

How would I display the time that is left until the date reaches 24 hours?

example:
16 hours 8 min(s) until you get me back.

$str='20060320185637';
$year = substr($str,0,4);
$month = substr($str,4,2);
$day = substr($str,6,2);
$day_a = $day + 1;
$hour = substr($str,8,2);
$min = substr($str,10,2);
$sec = substr($str,12,2);
$when = mktime($hour,$min,$sec,$month,$day,$year);
$now = mktime($hour,$min,$sec,$month,$day_a,$year);

// This is as far as I got but I think im making this to complicated.

If you can get the date stamp in a more useful format (a Unix timestamp, for example), that would take care of the bulk of your code straight off. Then you could just have

$when = strtotime('+24 hours', $str);

If you can't for some reason, the bulk of your code can still be got rid of:

list($y,$m,$d,$h,$i,$s) = sscanf($str, '%4d%2d%2d%2d%2d%2d');
$now = mktime($h,$i,$s,$m,$d,$y);

You can get $when the same way as before using $now, but since here you already have all the bits, you might as well take the easy route:

$when = mktime($h+24,$i,$s,$m,$d,$y);

(Here and before, note that 1 day is not necessarily 24 hours: decide what you actually mean and use that.)

Do $when - the current time to find out how many seconds there are to go, and from there on it's just the usual "divide by sixty and keep the remainder" business to convert that to minutes and seconds, and that to hours, minutes and seconds.

So now, you've got UNIX timestamps that are in seconds. now it's easy math:
Get the time difference

$left = $now-$when;

Start getting hours, minutes seconds

$hours = floor($left/(60*60));  // How many hours left
$left = $left-($hours*(60*60)); // Recalculate
$minutes = floor($left/60); // How many minutes left
$left = $left-$minutes*60; // Recalculate
$seconds = $left;

Now it's just a matter of displaying your information:

echo $hours.' hours '.$minutes.' min'.(($minutes>1)?'s':'').' until you get me back';

I must be missing something here, I put wp and bpat's code together and tried it and I always get ...

-24 hours 0 min until you get me back

Here is the link...

http://www.intheclassroom.org/tests/timetogetback.php

and the code

$str='20060320120000';
$when = strtotime('+24 hours', $str); 
list($y,$m,$d,$h,$i,$s) = sscanf($str, '%4d%2d%2d%2d%2d%2d');
$now = mktime($h,$i,$s,$m,$d,$y);
$when = mktime($h+24,$i,$s,$m,$d,$y);
$left = $now-$when; 
$hours = floor($left/(60*60));  // How many hours left
$left = $left-($hours*(60*60)); // Recalculate
$minutes = floor($left/60); // How many minutes left
$left = $left-$minutes*60; // Recalculate
$seconds = $left;
echo $now . "<br><br>";
echo $hours.' hours '.$minutes.' min'.(($minutes>1)?'s':'').' until you get me back'; 

Thanks,

The problem isn't with the code, it's with your date/time format. Take a look at it....

You define your $now with the timestamp you give it. Then you get the $when 24 hours after that. So no matter what, it'll always be 24 hours difference. To get the proper time, do this:

//      YYYYMMDDHHIISS
$str = '20060321151500';

$start = strtotime("now");
list($y,$m,$d,$h,$i,$s) = sscanf($str, '%4d%2d%2d%2d%2d%2d');
$end = mktime($h+24, $i, $s, $m, $d, $y);

$diff = $end-$start;

$hours = 60*60;
$minutes = 60;

$left['hours'] = floor($diff/$hours);
$diff = $diff-($hours*$left['hours']);

$left['minutes'] = floor($diff/$minutes);
$diff = $diff-($minutes*$left['minutes']);

$left['seconds'] = $diff;


foreach($left as $key=>$val)
{
	echo $val.' '.$key.' ';
}

{
    echo $val.' '.$key.' ';
}

Even using a fresh timestamp i still get "0 hours 0 minutes 0 seconds."

Am i missing something?

Also could not get the latter of other post to work either.

[bpat1434]

yeah, the most vital part: Where do you calculate how many seconds are between $start and $end?

Woops... looks like I missed it to...

Right after

$end=mktime

add

$diff = $end-$start;

As always, Bpat is right on the money.

I used your code and it works perfectly.

Thanks Bpat

By the way, since this is resolved, do I let the original author mark it resolved or do I do it?

Thanks,

Don

[bpat1434]

You can't, the original author is the only one that can (even though the button is still there).

[dmacman1962]

I did not know that.

Thanks again,

Don
