Adding different times in php

Question

Hello just a simple question here. Php's time related functions are confusing me ;-(

Given 2 variables

$start = "2013-07-25 20:24:13" ('Y-m-d H:i:s'); 
$duration = "0:55" ('H:i');

How may I add $duration to $start? should result in:

"2013-07-25 21:19:13"

Things would probably be infinitely less confusing if you only used timestamps except for when you need to display the date. — Ariane, Aug 22 '13 at 19:22

That's wat I came up with:$start = strtotime($start); $duration = explode(':', $duration); $end = date("Y-m-d H:i:s", strtotime('+'.$duration[0].' hour '.$duration[1].' minutes', $start)); — TNT_Larsn, Aug 23 '13 at 05:25

$dt = new DateTime('2013-07-25 20:24:13');
$dt->add(new DatePeriod('P55M'));
echo $dt->format('Y-m-d H:i:s');

+ Beat me. Note that the DateTime class is available in PHP 5.3+. – Jason McCreary Aug 22 '13 at 19:22
If people are still using 5.2 and developing new projects in it they should somewhat stop it @JasonMcCreary. Hell even 5.3 will be EOL next year. – PeeHaa Aug 22 '13 at 19:26

@PeeHaa, totally agree. Added for thoroughness. – Jason McCreary Aug 22 '13 at 19:28
$dt->add(new DatePeriod('P55M')); does not work because $duration is dynamic an can also be 1:15 – TNT_Larsn Aug 22 '13 at 19:33
@TNT_Larsn You'll need to convert that into hours and minutes which is easy to do (`explode()`). The above example just shows you how to do the math. – John Conde Aug 22 '13 at 19:37
