The problem is finding a way to expand the input name (which is a

reverse, iterate through $_POST to find a match for the input name and
get that value.
Try this overly commented snippet on for size...

Very nice, thank you. I was hoping there would be a way to do it
without resorting to eval(), but if even you can't figure out how, I'm
not going to waste any more time trying to either :)
You probably could by breaking it into each part and then using a loop
to descend to the right place, but I don't think that's going to be any
better than using eval.
I'm assuming the source for $target is trusted. If not then you'll want
to sanitise it further by removing anything that's not a-z, 0-9 and []
just to ensure no dodgy code can be inserted.
I loved this part:
// The target - offensive American spelling!
:)
Cheers,
No probs.
