What date/time functions to use for PHP 5.2

I want to add a duration to a date, I set this code :

$date = new DateTime(Date('r'));
$date = $date->format("d-m-Y H:i:s");                       
$interval = new DateInterval('PT1H2M3S');        
$date = $date->add($interval);        
echo $date;

and I get this error : Class ‘DateInterval’ not found

Why is this and how can I modify the date without DateInterval?

Answer 1

I use strtotime. Maybe not the best, but certainly the easiest way:

echo date("d-m-Y H:i:s",strtotime("2012-02-15 1 hour 2 min 3 sec"));

or if you need the interval from now use just:

echo date("d-m-Y H:i:s",strtotime("1 hour 2 min 3 sec"));
