My "fecha actual" is current date, so when i select that option lets say in 02/08/2015 (dd-mm-yy) and the second date to 04/08/2015 it returns one day but if i pick the first date manually (same 02/08/2015) it returns two days.
Examples: http://monopolo11.ninja/tests/imgs/ (the photos are there since i could put it in the post because of my low reputation)
Why is this happening?

Solution
You always override the $date1 var.
if ($tipfech == "actual"){
$yr1 = date("Y");
$month = date("m");
$day1 = date("d");
$date1 = new DateTime("$yr1-$month-$day1");
}
$date1 = new DateTime("$da1");
When you don't fill manually the start date, then new DateTime is created with argument NULL. It returns the current date but with the time actual.
This cause a compute day rounded down (because less of 48 hours).
