Variable SESSION variables

Question about variable variables and using session variables for them. O.K. So if I have:

 

$foo = 3;

$_SESSION['bar'] = "foo";

 

$$_SESSION['bar']  should equal the value of $foo, however I can't get it to work. Can someone tell me what I am doing wrong..... is it formatting???

 

Thanks,

Thomas

o.k. sorry, didn't realize I didn't write it out completely (need more coffee) ...

 

The above answer works, however I'm taking it a step further. The problem is if $foo is a session variable, how do I declare that in the $_SESSION['bar']?

 

$_SESSION['foo'] = 3;

$_SESSION['bar'] = 'foo';// <--- problem area value of "foo" declaration

echo $$_SESSION['bar'];
