Re: RFC: Stop to automatically cast numeric-string to int when using them as array-key

This is not something that should be changed in an advanced > version of the language. > Would you still consider this as a massive BC break if - The type of the key don't change anymore i.e. array_search(0, ['10' => 0]) will be '10' and not 10. - $array[10] still return $array[10] ?? $array['10'] - $array['10'] still return $array['10'] ?? $array[10] so it still cast the value when accessing to an array key, but when using array_keys/array_search/array_flip/... it won't be cast anymore.
