I came across the interesting notion of $a and $$a, which in turns uses
the string in $a as a $-suffix to make a new dynamic variable.
Can someone illustrate a practical use out of it? I will be very curious
to see one (webdesign related) example of its usage.
Thanks,

There's hardly a reason to use them. Often enough they are misused in
situations where an array would be much more appropriate.

I agree with Micha. Variable variables are a solution looking for a
problem. It creates code which is very difficult to manage and update,
and should not be used.

Thanks for the reply. I will stop taxing my brain on the use of variable
variables :)
