Errrr.... I used the wrong variables in the previous message. I also
assumed that the start and end times are actually TIME and not strings
(which appears to be the case since you are subtracting one from the
other). If the start and end AREN'T time types you would have to
convert them first. You should be able to use 'strtotime' or mktime to
convert them to time type.
Also, the gmstrtime used above would limit the time to 24 hours. If
there is a possibility that the difference in time might be more than
24 hours you can do something like this:
printf( "%d days %s", (int)($tot_time / 86400), gmstrftime(
"%H:%M:%S", $tot_time ) );
So, here is what I probably should have posted:
<?PHP
$tot_time = ($data['end_time'] - $data['start_time']);
echo strftime( "%H:%M:%S", $data['end_time'] ) . " - ";
echo strftime( "%H:%M:%S", $data['start_time'] ) . " = ";
printf( "%d days %s", (int)($tot_time / 86400),
gmstrftime( "%H:%M:%S", $tot_time ) );
?>
