How to append dynamic array key to another array key

Question

Sorry for the bad title, it's really hard to describe,

$x['is']['tall'] = 'yes';
$y['personal']['age'] = 30;

I have dynamic array keys, and I want to it append to another array key, the result is like

$main['profile']['is']['tall'] = 'yes';                                                                                                                                                                         
$main['profile']['personal']['age'] = 30;

cause when I use json_encode I want to the structure like {"profile":{"is":{"tall":"yes"},"personal":{"age":30}}}

I don't know how to extend the array key like that.

If you have:

$x['is']['tall'] = 'yes';
$y['personal']['age'] = 30;

Then you can just merge $x and $y to $main like:

$main['profile'] = array_merge($x, $y);

var_dump($main);

echo json_encode($main);

Output:

array(1) {
  ["profile"]=>
  array(2) {
    ["is"]=>
    array(1) {
      ["tall"]=>
      string(3) "yes"
    }
    ["personal"]=>
    array(1) {
      ["age"]=>
      int(30)
    }
  }
}
{"profile":{"is":{"tall":"yes"},"personal":{"age":30}}}

Yeah. I think I need more coffee. This is how it should be done.
