This the simpliest function I could come up with for getting the
difference between two dates. Note that I didn't code any error
checking.

<?php
echo date_diff ("20051210", "20051230");

function date_diff($s,$e)
{
return((strtotime($e) - strtotime($s))/86400);
}
?>

Since the strtotime() function returns the number of seconds since
1/1/1970, you need to divide the result by the number of seconds in a
day (86400) to get the number of days.
