    QuickHashIntStringHash::set

    (PECL quickhash >= Unknown)

    QuickHashIntStringHash::set — This method updates an entry in the hash with a new value, or adds a new one if the entry doesn't exist

    説明

    public QuickHashIntStringHash::set(int $key, string $value): int

    This method tries to update an entry with a new value. In case the entry did not yet exist, it will instead add a new entry. It returns whether the entry was added or update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashIntStringHash::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 add or update.

    value

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

    戻り値

    2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.

    var_dump( $hash->set( 46692, "twenty nine thousand nine hundred six" ) );
