formatting time: minutes to hours

[Anon]

Hello,

I've been reading the PHP manual and visiting PHP forums to study the digests, but I am still having a problem formatting minutes to days/hours/minutes

I have PHP code that returns a difference between two times in minutes.

---

$currenttime = time();
echo "Current time: ". strftime("%Hh%M %A %d %b" ,$currenttime)."<br>";
echo "Open Time: ". strftime("%Hh%M %A %d %b" ,$theDate)."<br>";
$temptime = DateDiff ("n",$theDate,$currenttime);

print "$temptime";

The calculation works fine and displays the difference between the two times in minutes. However, I want to format the minutes to display the time in days : hours :minutes.

Example, 4000 minutes is currently displayed as '4000 minutes'
I want it to be displayed like:
1 day, 6 hours, 40 minutes

I have studied 'strftime()', but I can't seem to find my answer.

Is 'strftime()' the function that will do this, and if so, how can it be used to create complex output as I desire?

Thanks,
Bill

I don't think there are built-in functions for what you want. I might have missed them of course, but by my knowledge, you'll have to do this yourself.

Like this, for example:

$minutes = 7000;
$hours = floor($minutes / 60);
$minutes -= ($hours * 60);
print "$hours:$minutes";

Not to complicated, I think?

There may be other ways of getting what you want, but it's fairly simple to do using simple math with division (/) and the modulus operator (%). The modulus operator returns the remainder of a division. A division returns a floating-point number, so you have to cast it to an integer.

Try this code:

<?
echo "<pre>4 days, 2 hours, 24 minutes, 10 seconds\n";

// total up the number of seconds in this span

$timedata = 10 + (2460) + (26060) + (4 24 60 60);

// now here's how to reconstruct it

$days = (int) ($timedata / (24 60 60));

// find the remainder of that operation
$remainder = $timedata % (24 60 60);

// now find the hours in the remainder
$hours = (int) ($remainder / (60 * 60));

// and the remainder of THAT operation
$remainder = $remainder % (60 * 60);

// now we're down to minutes
$minutes = (int)($remainder / 60);

// and what remains is ...
$seconds = $remainder % 60;

echo "$days days, $hours hours, $minutes minutes, $seconds seconds</pre>";
?>

Thank you both for your input. I found the information very helpful and I have been able to work it out with some simple division.
