$mm=$_POST[month];

$mm = str_pad($mm, 2, '0', 1); // If it is less than 2 characters long, add a 0 on the left side

$yy=$_POST[year];

$j=$dd . "-" . $mm . "-" . $yy . ".html";

echo "<a href=<?$def_dir/$j?>clickhere</a>";

$month = strtolower(date('M', strtotime("$yy$mm$dd 12:00:00"))); // A lot going on here

// strtolower makes the results all lowercase to match your 'mar' for march

// date('M', ...) returns the 3-letter form of month

// strtotime() is returning the unix timestamp for date() for the submitted date, at 12 noon.

$def_dir="/var/www/html/backup/$month";

?>
