PHP: 'rotate' an array?

Question

is it possible to easily 'rotate' an array in PHP ?

Like this: 1, 2, 3, 4 -> 2, 3 ,4 ,1

Is there some kind of built-in PHP function for this?

Answer 1

  $numbers = array(1,2,3,4);   array_push($numbers, array_shift($numbers));   print_r($numbers); 

Output

Array (     [0] => 2     [1] => 3     [2] => 4     [3] => 1 )
