Sanitize array using WordPress sanitization functions

Here is the array I need to sanitize.

$array = array(
    'key_1' => 'array elemnt 1',
    'key_2' => 'array element 2'
);

Now I need to sanitize array key & value using same sanitization function. If so, we can use array_map function.

$new_array = array_map('sanitize_key', $array);

But some times, I need to sanitize array key & values using different sanitization functions.

$array = array(
    'key_1' => 'array elemnt 1',
    'key_2' => 'array element 2'
);

$keys = array_keys($array);
$keys = array_map('sanitize_key', $keys);

$values = array_values($array);
$values = array_map('sanitize_text_field', $values);

$array = array_combine($keys, $values);
