How delete array elements from string

Question

I need to delete a key in an array from a string.

String is translations.fr

Array is

[
    ...,
    translations => [
          fr => [
              ...
          ],
          es => [
              ...
          ]
    ],
    ...,
]

Result must be :

[
    ...,
    translations => [
          es => [
              ...
          ]
    ],
    ...,
]

I think, using exlpode and unset is the good way.

Can you help me ? Thank's

Solution :

public function deleteKeyV3($keyToDelete) {
    $keys = explode('.', $keyToDelete);
    $result = &$array;

    foreach ($keys as $key) {
        if (isset($result[$key])) {
            if ($key == end($keys)) {
                unset($result[$key]);
            } else {
                $result = &$result[$key];
            }
        }
    }
}
