Question

In my PHP application I want to calculate the sum of two time variables. I am looking for something like this example.

$time1 = 15:20:00;
$time2 = 00:30:00;
$time = $time1+$time2;

Answer 1

The best way to do this is most likely to use strtotime to convert them to timestamps and then do the adding together:

$o = strtotime($time1)+strtotime($time2);

If I remember right strtotime does support this format.

Otherwise you will need to filter it out yourself.
