Get total time difference between two dates using php [duplicate]

Answer 1

If you are using or able to use PHP 5.3.x or later, you can use its DateTime object functionality:

$date_a = new DateTime('2010-10-20 08:10:00');
$date_b = new DateTime('2008-12-13 10:42:00');

$interval = date_diff($date_a,$date_b);

echo $interval->format('%h:%i:%s');

You can play with the format in a variety of ways, and once you have dates in DateTime objects, you can take advantage of a lot of different functionality, for example comparison via normal operators. See the manual for more: http://us3.php.net/manual/en/datetime.diff.php

Answer 2

You can use the the strtotime function to turn the time to integers and subtract them.

$time1 = strtotime("2008-12-13 10:42:00");
$time2 = strtotime("2010-10-20 08:10:00");

$diff = $time2-$time1;
// the difference in int. then you can divide by 60,60,24 and 
// so on to get the h:m:s out of it

Answer 3

what im using:

$seconds = strtotime("2010-10-20 08:10:00") - strtotime("2008-12-13 10:42:00");

$days    = floor($seconds / 86400);
$hours   = floor(($seconds - ($days * 86400)) / 3600);
$minutes = floor(($seconds - ($days * 86400) - ($hours * 3600))/60);
$seconds = floor(($seconds - ($days * 86400) - ($hours * 3600) - ($minutes*60)));

you can format now in your way
