strtotime syntax problem?

[jeffcool]

This is my first try at using strtotime, and I just can\'t seem to get this to work. Lets say I have:
$foo = 2002-04-10;

print date(\"Y-m-d\", strtotime(\'2002-04-10 + 3 days\'));

Gives me: 2002-04-13

That\'s what I expect, however in my case I don\'t know that the date is 2002-04-10 so I want to replace the date with $foo

print date(\"Y-m-d\", strtotime(\'$foo\' + \'+ 3 days\')

Gives me: 2002-04-09 (todays date)

Any ideas how to make this work?

$foo = date("Y-m-d", mktime());

Never mind... after a few minutes doing something else, it occured to me what I was doing wrong - doh

print date("Y-m-d", strtotime($foo .'+ 3 days'));
