Generate nested array from string

Question

I want to generate a nested array from a string.

The String looks like this $item = "profile:my_wallet:btn_recharge";

I want to convert it to nested array like this ["profile"]["my_wallet"]["btn_recharge"]

Does the php explode() function work for you? [explode()](https://www.php.net/manual/en/function.explode.php) — Rob Moll, Apr 15 '21 at 12:57
Yes, that is possible. Do you have some code you want help with, or are you looking for a developer to pay to write it for you? — IMSoP, Apr 15 '21 at 13:00

What you could use is a simple recursion to go as deep as you like.

function append(array $items, array $array = []): array
{
    $key = array_shift($items);
    if (!$key) return $array;
    $array[$key] = append($items, $array);
    return $array;
}

$array = append(explode(':', "profile:my_wallet:btn_recharge"));

The result of $array looks like below and can be accessed as you asked

$array['profile']['my_wallet']['btn_recharge'];

array (
  'profile' =>
  array (
    'my_wallet' =>
    array (
      'btn_recharge' =>
      array (
      ),
    ),
  ),
)
