Adding minutes to a timestamp

Hi


How can I add 15 minutes to the previous event time (timestamp) to get the next event time.
Note: This event time is not in a table.

Straight forward adding the two values will probly not provide the correct result.

I can get the correct time with Mysql addtime($time, $duration) but that
is only good if the if info is in a table.

Thanks

<?php
$time = "09:00:00";//timestamp hh:mm:ss
$duration = 00:15:00;//enent duration hh:mm:ss


$next_time = $event_time + $event_duration;
?>

PHP:

 

i would use the unix timestamp which is in seconds, then add 900.

$now=time();

#there are 900 seconds in 15 minutes

$fifteenminutes=$now + 900;

now use the date function to format your time

 

that's what I would do as well

 

Or if you have a specific time, convert to a timestamp then add 900 seconds.
$timestamp=mktime ( $hr,$min,$sec, etc. );
$fifteenminutes= $timestamp +900;

 

If you wanna use timestamps (usually it's easier, but not always), use strtotime

 

Hi

You are great!
Thanks for the suggestion.
This is the final code that solved the problem

<?
	$event_time = 09:00:00
	$event_length = 15;
	
	$timestamp = strtotime("$event_time");
	$etime = strtotime("+$event_length minutes", $timestamp);
	$next_time = date('H:i:s', $etime);
?>
