For loop to fill an array

[phpscott]

I am trying to make a selection order array for an unknown (but no more than 12) amount of items.  The resulting list for x items would be:

 

1 2 3 4 5 6 x  (sequential up to x)

x 6 5 4 3 2 1  (reverse the list from before)

 

2 3 4 5 6 x 1  (start with the next number and go thru the whole list)

1 x 6 5 4 3 2  (reverse the list from before)

 

3 4 5 6 x 1 2  (start with the next number and go thru the whole list)

2 1 x 6 5 4 3  (reverse the list from before)

 

and so on until we have started with each number.  X would be an input from the user.

 

Thanks!
