$length will be 5 days and

$lengthFromEnd will be -1 days.

but my code return abnormal result

Answer 1

you can also try this way.

$difference = $start_date->diff($end_date)->days;

Answer 2

For negative result, you need a add parameter, like this:

$absolute = false;
$end->diffInDays($now, $absolute);
