Question

i have two time values say starttime=23:00:00 and estimation time=00:45:00 now i want to add starttime and estimation time and store it in a variable i did like this

$add = abs(strtotime($starttime) + strtotime($estimationtime));

{
$message=array("message"=>"there is an appointment");
}

if i echo $add i am not getting the right format it shows 2675756700 pls help me to solve this

If you want to echo your $add variable in a readable form you have to format it first.

echo(date("H:i:s", $add));
