This code gives the effect i wont but i need to get the two times from the database then get the result
the time was posted in the database as this format time(h,m,s)

so what i need is to get that info out of the database in the below code format but how thank you.

[code]
<?
// Pass epoch timestamps
function calcDateDiff ($date1 = 0, $date2 = 0) {

   // $date1 needs to be greater than $date2.
   // Otherwise you'll get negative results.
   if ($date2 > $date1)
       return FALSE;

   $seconds  = $date1 - $date2;

   // Calculate each piece using simple subtraction

   $weeks     = floor($seconds / 604800);
   $seconds -= $weeks * 604800;

   $days       = floor($seconds / 86400);
   $seconds -= $days * 86400;

   $hours      = floor($seconds / 3600);
   $seconds -= $hours * 3600;

   $minutes   = floor($seconds / 60);
   $seconds -= $minutes * 60;

   // Return an associative array of results
   return array( "weeks" => $weeks, "days" => $days, "hours" => $hours, "minutes" =>

$minutes, "seconds" => $seconds);
}


// Example: current timestamp with 22:00 12th, January 2003 or use variable(s)
if ($diff = calcDateDiff(time(), mktime(22, 00, 00, 1, 12, 2003))) {
   //Format output any way you like
   printf("Difference between the two dates is: %d week(s), %d day(s), %d hour(s), %d

minute(s), %d second(s).", $diff['weeks'], $diff['days'], $diff['hours'],

$diff['minutes'], $diff['seconds']);
}
?>
[/code]
