Can someone point me in the right direction on how to add time in PHP.

For example:

The format would be like this
Code:

1:02.8 (1 minute, 2 seconds, 8 1/10ths) 1:05.2

I need to add that to get 2:08.0 (2 minutes, 8 seconds)

Then, I'll need to divide that number by the number of races run for the average time per race (which in this case would be (1:04.0)

Is this possible in PHP?

Thanks.

Brian


Of course - anything's possible in PHP  

[Sorry - been a long day's drive and it has warped my sense of humour]

The best way to deal with time arithemetic (in any language) is to convert to seconds, do the sums, and convert back again.  I would suggest a regular expression match to extract the minutes and seconds, multipy the minutes by 60 and add the seconds, do the maths, and use the / and % operators to convert back, followed by sprintf.

Would you like me to code an example?  Too tired to do so tonight (It's 11 pm in Dublin where I am) but I could do so tomorrow evening ....


Graham,

I can strip it down to seconds...but would need some help getting it back into a time format.

Any help would be greatly appreciated.

(hope you get a good night's sleep!

Example of formatting a time in seconds into minutes and seconds, as per your format:

Code:

<form> <input name=seconds> </form> <?php if ($seconds > 0) {        $mins = floor ($seconds / 60);        $secs = $seconds % 60;        printf ("%.2f seconds should display as %d:%02.1f<br>",                $seconds, $mins, $secs);        } ?>

Got a good night's sleep, yes, thanks ... much recovered now (24 hours later).

thanks, Graham.  Pretty easy to understand now that I see it in front of my face.  I appreciate it!
