I got stuck how to generate array like this from 4 input values.
As = first position = 12
Kop = second position = 34
Kepala = third position = 56
ekor = fourth position = 78
User will be able to any number into those position (input) or sometime some field can be blank.
I would like the those 4 input values combine together and form as 4D, 3D and 2D number. But make sure the position cannot be change and the generate number cannot duplicate.
Example:
- number 1 and 2 are on first position ever.
- number 3 and 4 are on second position ever.
- number 5 and 6 are on third position ever.
- number 7 and 8 are on fourth position ever.
Source code (PHP or JS) or Idea both are appreciated.
