Array shuffle with step

[silkfire]

How does one create a function that shuffles a numerical array X amount of steps?

 

Example:

 

$array = array('item1', 'item2', 'item3', 'item4');

 

$array = array_shuffle($array, 2);

 

Result should be:

array('item3', 'item4', 'item1', 'item2')

 

Function looks like: array_shuffle($array, $steps, $direction = 1);

 

$direction is 1 for forward or 0 for backwards.

 

Is this hard?

No, you just need to use a combination of array_pop and array_unshift in one direction and array_shift and array_push in the other.
