Help me please

[Jens14]

function date_diff($str_start, $str_end)
{

$str_start = strtotime($str_start);
$str_end = strtotime($str_end);

$nseconds = $str_end - $str_start;
$ndays = round($nseconds / 86400);
$nseconds = $nseconds % 86400;
$nhours = round($nseconds / 3600);
$nseconds = $nseconds % 3600;
$nminutes = round($nseconds / 60);
$nseconds = $nseconds % 60;

if ($ndays != 0)
{
echo $ndays." days, ".$nhours." hours, ".$nminutes." minutes, ".$nseconds."
seconds.<br>\n";
}
if ($ndays = 0)
{
echo $nhours." hours, ".$nminutes." minutes, ".$nseconds."
seconds.<br>\n";
}
}

date_diff("2007/03/14 13:15:45", "2007/03/16 14:00:00");
date_diff("2007/03/16 13:45:00", "2007/03/16 14:00:00");

This is the code of my function, what I need is that when days are 0, it only needs to show hours, minutes and seconds, when days and hours are 0 only minutes and seconds, when days, hours and minutes are 0 it only needs to show seconds, I've made a start but even that doesn't work.

Can anyone help?

If you're comparing, use "==" not "="....

Have a look at mktime in the manual:

http://us3.php.net/mktime

Check out some of the code snippets below, the main features already do much of what you are doing by hand here.

Also, negative numbers are nice (like a count down 'til when you are married, then tells you how long you have been married)

Have fun

My problem is that I need an array, that gives the seconds etc. in the way I described.

Thanks, bpat1434 by the way, you've helped me hehe.
