If a key from two arrays is the same in an array_merge() function, sub merge those two key's values. array_merge() currently just replaces the other key.

Here is an example of the current behavior.

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

var_dump(array_merge($a, $b));

----------------------------------

array(1) {
  ["x"]=>
  array(3) {
    [0]=>
    int(4)

    [1]=>
    int(5)

    [2]=>
    int(6)
  }
}
-------------

I would want it the output to be..

array(1) {
  ["x"]=>
  array(3) {
    [0]=>
    int(1)

    [1]=>
    int(2)

    [2]=>
    int(3)

    [3]=>
    int(4)

    [4]=>
    int(5)

    [5]=>
    int(6)
  }
}
