I'm pulling the length of a video out of a database, that is in the format 00:00:00

I then want to add 15 minutes to that time to allot for total time required.  I can't quite seem to get there.

$videotime = mysql_result($res2,$b, 0);
$quiztime = "00:15:00";


                  echo "Video time is: " . $videotime . '<br />';
                  echo "Quiz length is: " . $quiztime . '<br />';
            
                  // $duration = mktime ($videotime + $quiztime);
                  // $duration = date("i:s", $duration);
                  
                  $hours_diff = ((strtotime($videotime)) + (strtotime($quiztime)));
                  echo  date('h:i:s', $hours_diff)." Minutes";
            
                  echo '<br /><br />';

strtotime returns the time relative to today. So "00:15:00" is equal to March 30, 2012 12:15:00am and your video length would be equally that time past midnight this morning. You will need to eliminate today's date in order to add the additional 15 minutes. You also need to format your date for a 24 hour clock.
$videotime = "00:05:00";
$quiztime = "00:15:00";
$zerohour = "00:00:00";

echo "Video time is: " . date('m d, Y H:i:s',strtotime($videotime) ) . '<br />';
echo "Quiz length is: " . date('m d, Y H:i:s',strtotime($quiztime) ) . '<br />';
echo "Zero hour is: " . date('m d, Y H:i:s',strtotime($zerohour) ) . '<br />';

$hours_diff = ((strtotime($videotime) ) + (strtotime($quiztime)-strtotime($zerohour) ));
echo  date('H:i:s', $hours_diff)." Minutes";

Open in new window

This will not work if your video length should ever be more than 23:45:00. But I doubt that will be a problem.
