Thanks, any idea where this is described in the PHP manual? Searching
for "$$" produces no results.

This code fragment will produce a variable such as $yellow_7, for example,
where $aNumber is equal to 7. Then use it as any other variable.
${'yellow_' . $aNumber} = "assign something";
I've posted this example before, however, and the general consensus seems to
be to just use an array.
