To change values in a multi-dimensional array while looping through:

$var=array('a'=>array(1,2,3),'b'=>array(4,5,6));

foreach ($var as &$sub) {
  foreach ($sub as &$element) {
    $element=$element+1;
  }
}

var_dump($var);

------------------------------
produces:
------------------------------
array(2) {
  ["a"]=>
  array(3) {
    [0]=>
    int(2)
    [1]=>
    int(3)
    [2]=>
    int(4)
  }
  ["b"]=>
  array(3) {
    [0]=>
    int(5)
    [1]=>
    int(6)
    [2]=>
    int(7)
  }
}
