Adding a number of days to a date

[elentz]

How can I take a date and add a set amount of days to it.  What I am after is I have a CRM system that will generate the date of an invoice, I want to have a new field to add 10 days to that date.  IE Invoice date 10-1-2007  and the Due date 10-11-2007.

 

Thanks!

$date = date('Y-m-d', strtotime("+10 days"));

 

EDIT:

 

If you want to add days to a specific date, then you can do this

 

<?php

$date = strtotime("2007-11-14");
$date = date('Y-m-d', strtotime("10 day", $date));
echo $date;

?>

Would that work with a variable ? Instead of the static date?

 

Thanks
