I have 2 unix time, one is todays date and other is expiration time.

  • Todays Time: 1377173245 (2013-08-22 12:07:25)
  • Expiration Time: 1406303166 (2014-07-25 15:46:06)

What I want to achieve is calculate remaining time to expire the listing. In current case, it should show, 11 months -- hours -- minutes -- seconds I didn't find any good solution to calculate the difference. I doubt is it possible to calculate time difference using UNIX time system?

Thank you :-)

This is what you're looking for: DateTime::diff

First create object with 1st date:

$date = new DateTime('2013-08-22 12:07:25');

Then use the diff method:

$diff = $date->diff(new DateTime('2014-07-25 15:46:06'));

Now if you print $diff variable, you will see the array containing values for hour, minute, day and so on.

  • Hello Michal, it show the following error, Call to undefined method DateTime::diff() – prototype Aug 22 '13 at 12:33
  • Oh.. I see it require php 5.3 or higher – prototype Aug 22 '13 at 12:35
  • Ya, its working. thanks a lot friend I appreciate. Also, thank you everyone who suggested the answers. – prototype Aug 22 '13 at 12:41
  • If all you need to check is whether the expiration date-time has been crossed, simply check the "invert" index from the $diff array. If its 1. then the returned interval is negative and hence the expiration limit has been crossed. – jahackbeth May 17 '15 at 20:03

Use DateTime::diff

See the doc on https://www.php.net/manual/en/datetime.diff.php

Try using datetime::diff. Here's the example from the php.net documentation:

<?php
$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);
echo $interval->format('%R%a days');
?>

It's easy to create a DateTime object using a timespamp. However, this solution requires PHP 5.3+.

Use DateTime class:

Example:

$datetime1 = new DateTime();
$datetime2 = new DateTime('2014-07-25 15:46:06');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%M months, %H hours, %I minutes, and %S seconds remaining ');

Outputs:

11 months, 21 hours, 44 minutes, and 20 seconds remaining

It is most definitely possible. However, you'll run into problems with months, because there are different number of days in each month, so I'll just do days, hours, minutes, and seconds below.

$days=($expiration-$today)/(60*60*24);
$hours=(($expiration-$today)/(60*60))%24; //the modulus operator, gets a remainder
$minutes=(($expiration-$today)/(60))%(60*60);
$seconds=($expiration-$today)/60;

If you need months, you'll find it easier to use date_diff().
