PHP Adding 15 minutes to Time value

Question

I have a form that receives a time value:

$selectedTime = $_REQUEST['time'];

The time is in this format - 9:15:00 - which is 9:15am. I then need to add 15 minutes to this and store that in a separate variable but I'm stumped.

I'm trying to use strtotime without success, e.g.:

$endTime = strtotime("+15 minutes",strtotime($selectedTime)));

but that won't parse.

strtotime returns the current timestamp and date is to format timestamp

  $date=strtotime(date("h:i:sa"))+900;//15*60=900 seconds
  $date=date("h:i:sa",$date);

This will add 15 mins to the current time

Quite easy

$timestring = '09:15:00';
echo date('h:i:s', strtotime($timestring) + (15 * 60));
