If you're still not clear try thinking of it like this:

$one = "banana"
$two = "one"

echo $two; // gives "one"

but

echo $$two; // gives "banana"

This is because
* PHP looks at "$$two" and, working right to left, substitutes the value of
"$two"
* "$$two" now becomes "$one"
* PHP goes a step further and looks to see what is in "$one" and comes up
with "banana"

Any clearer? I don't suppose so :-)
