    QuickHashStringIntHash::update — This method updates an entry in the hash with a new value

    説明

    public QuickHashStringIntHash::update(string $key, int $value): bool

    This method updates an entry with a new value, and returns whether the entry was update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashStringIntHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

    パラメータ

    key
    The key of the entry to update.
    value
    The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.

    戻り値

    true when the entry was found and updated, and false if the entry was not part of the hash already.
