I have done some filtering in an array using unset. The problem is that if I do a var_dump on the array after the filtering, then some of the keys are missing. Eg, key 2 isn't showing.
So what I would like to do is to remap the keys so that Key 3 will turn into Key 2, Key 5 will turn into Key 4 etc. Basicly so I can do some loops later on with the array re-mapped later on.
