Why not?
2. You controll the name of the array keys with the form. Why is there any need to change them form PHP's side of things?
That's an assumption. A reasonable one in most cases, but not necessarily the case.
3. I'm not sure Roberts solution would work. I think it might result in an endless loop, and timeout your script.
I always worry about adding or removing elements while iterating through an array. I generally build up an array of keys to remove and remove them in a separate loop afterwards just to be on the safe side.
