Question

• Add time in PHP 4 answers

Following is code that helps in adding specific hours in present time

date('H:i', strtotime('+1 hours'));

How should i add hours if the time and hours are dynamic. E.g I wish to add 2 hours to time 08:00, but these both things are saved in variables

$hours = "2";

$day_time = "08:00";

I tried the following but didn't work

$new_time = date($day_time, strtotime('+$hours hours'));

can anyone please tell how it can be done

echo date("H:i", strtotime("+{$hours}hour ".$day_time));
