[SOLVED] Trying to find difference in hours- edit code from days to hours?

[kernelgpf]

Here's my code- I'm trying to find the difference in hours between one date from another, and my code currently finds the difference in days- could somebody edit the code to use hours instead of days?

 

$expirationdate[0] = $row3[datetillcompletion];
$startdate[0] = date('Y-m-d');

$startdate = strtotime($startdate[0]);
$expirationdate = strtotime($expirationdate[0]);
$delta = $expirationdate - $startdate;

$final=round($delta/86400);

How many seconds in a day? 86400. How many seconds in an hour? 3600:

 

$final=round($delta/3600);
