calculating no. of nights

[Anon]

how do i get difference between two dates
where both are key in by user,
like below, and format is dd/mm/yyyy
<input type="text" name="FromDate">
<input type="text" name="ToDate">

i converted to unix, timestamp. but i dont know how to get the difference,

$date_el_FD = explode("/" ,$FromDate);
$date_el_TD = explode("/" ,$ToDate);

$FD = mktime (0, 0,0 ,$date_el_FD [1], $date_el_FD [0],$date_el_FD [2]);
echo $FD;
echo "
";
$TD = mktime (0, 0,0 ,$date_el_TD [1], $date_el_TD [0],$date_el_TD [2]);
echo $TD;
$diff = ($FD-$TD);
echo "
";

echo strftime("%Hh %M %A %d %b", $diff);

$diff = ($FD-$TD);

Should be the other way around. ToDate minutes the FromDate

echo strftime("%Hh %M %A %d %b", $diff);

Why are you outputting %H, %M, etc? You only need %d if you're calculating the number of nights...

Do those changes and it will run OK.

thanks,

but it is giving incorrect results,

like todate = 05/02/2002
fromdate = 02/02/2002

is returning 04 but that is ok

but todate = 05/03/2002
fromdate = 02/02/2002

is returning 01

please check thanks,

I need to do this only i need to test to see how many minutes there are from timeA to timeB. ANy help?

[Anon]

Well, instead of %d use %m I think. Check out the strftime format codes at php.net

Try this:

<?

$FromDate = "2/2/2002";
$ToDate = "5/3/2002";

$date_el_FD = explode("/" ,$FromDate);
$date_el_TD = explode("/" ,$ToDate);

$FD = mktime (0, 0,0 ,$date_el_FD [1], $date_el_FD [0],$date_el_FD [2]);
$TD = mktime (0, 0,0 ,$date_el_TD [1], $date_el_TD [0],$date_el_TD [2]);
$diff = ($TD-$FD);

$d = getdate($diff);
$d['year'] = $d['year'] - 1970; // get rid of Epoch time
print $d['year']*365 + $d['yday'];

?>

That will actually give you an approximation when the dates are more than 1 year appart. The reason is because I didn't take into account when the year is 366 days long. But it shouldn't be hard to implement, so I'll leave it to you.
