That won't work as there is nothing to increment the date within the for
loop:

for (<set variable>;<exit condition>;<condition modifier>);

You would need some that would take the date and increment it. One
output would be to use the mktime function to convert the date into
timestamp and then use that for the comparison

function from_date($date) {
  list($year, $month, $date) = explode("-", $date) {
  return mktime(0, 0, 0, $month, $day, $year);
}

function to_date($date) {
  return date("Y-m-d", $date);
}

$dt='2003-04-22';
$to='2003-04-30';

for ( ; from_date($dt) > from_date($to); $dt = to_date(from_date($dt)+(60*60*24))) {
  print "XYz";
}

--8<--------------

I'm not sure if PHP can handle dates like you want, but that's one way
around the problem....
