I do believe this has all the pieces you are looking for ... dates are a bit tricky to work with.

<?php
// PART ONE
// creating a drop down with only the days in this month
$today = new DateTime();
$days = $today->format('t');
print "<select name=\"days\">\n";
for ( $i = 1; $i <= $days; $i ++ ) {
  print "  <option value=\"$i\">$i</option>\n";
}
print "</select>\n";

print <<<ENDINPUT
<select name="stay">
  <option value="1">1</option>
  <option value="2">2</option>
  <option value="3">3</option>
  <option value="4">4</option>
  <option value="5">5</option>
  <option value="">...</option>
</select>
<br />
ENDINPUT;

// PART TWO
// parsing the input
$day = $_POST['days'];
$for = $_POST['stay'];
$day = 12; // for testing
$for = 4; // for testing

$today = $today = new DateTime();
$year = $today->format('Y');
$month = $today->format('n');

$delta = new DateTime( "$year-$month-$day" );

$omega = new DateTime( "$year-$month-$day" );
$omega->modify( "+$for day" );

while ( ( $delta->format('Ymd') + 0 ) < ( 0 + $omega->format('Ymd') ) ) {

  // see this page for all available date formats
  // http://us3.php.net/manual/en/function.date.php
	
  print $delta->format( 'F d Y' )."<br>\n"; // example code
  $delta->modify( "+1 day" ); // REQUIRED CODE
}
?>

You should probably modify the days drop down to only display the days from the current day to the last day of the current month -- I'll leave that part to you so you get the hands-on experience. ;-)

Hope this helps

Yep, DAteTime() is PHP 5 (PHP 5 >= 5.1.0) as per the documentation.

The way I see it, you have two choices ...
1. Upgrade you PHP or have your server upgrade their PHP
2. Take a look at the older Date() functions in the documentation and try to do it some other way
http://www.php.net/manual/en/function.date.php
... I recommend the first choice personally.

Wish I could help more, but I'm in the middle of my own project tonight.

Good luck
