PHP: add seconds to a date

Question

I have $adate; which contains:

Tue Jan 4 07:59:59 2011 

I want to add to this date the following:

$duration=674165; // in seconds 

Once the seconds are added I need the result back into date format.

I don't know what I'm doing, but I am getting odd results.

Note: both variables are dynamic. Now they are equal to the values given, but next query they will have different values.

Answer 1

If you are using php 5.3+ you can use a new way to do it.

<?php  $date = new DateTime(); echo $date->getTimestamp(). "<br>"; $date->add(new DateInterval('PT674165S')); // adds 674165 secs echo $date->getTimestamp(); ?> 

Answer 2

Just use some nice PHP date/time functions:

$adate="Tue Jan 4 07:59:59 2011"; $duration=674165; $dateinsec=strtotime($adate); $newdate=$dateinsec+$duration; echo date('D M H:i:s Y',$newdate);
