Java Solution

class Solution {
    public int[] solution(int[] A, int K) {
        int[] rotate = new int[A.length];
        for(int i = 0; i < A.length; i++){
            rotate[(i+K)%A.length] = A[i];
        }
        return rotate;
    }
}

PHP Solution

function solution($A, $K) {
    $rotate = array();
    for($i = 0; $i < count($A); $i++){
        $key = ($i+$K)%count($A);
        $rotate[$key] = $A[$i];
    }
    return $rotate;
}
