Assign a variable with another variables value

["Martin Allan Jensen" <bailey@sprit.dk>]

Hi folks,

I probably need a little help the next couble of days, but well here is the first question.

How can i assign a variable with the value of another variable ??

Example:
$foo = "BAR";

$newBAR = "some string";

The BAR is supposed to be taken from the value of $foo.

THANKS A LOT!!!
