DateTime
If you are currently using php 5.2.x (The latest version in the Ubuntu repository is 5.2.4 as I write this), and need to add to a date, consider whether using DateTime::modify will work for you, as DateTime::add is only available from 5.3
DateTime::add
(PHP 5 >= 5.3.0)
DateTime::add — Adds an amount of days, months, years, hours, minutes and seconds to a DateTime object

echo '<br />'.$date->format("d-m-Y").' : 5 Days';
